Semiochemicals from Domestic Cat Urine and Feces Reduce Use of Scratching Surfaces

Scratching is a natural behavior in cats but can cause damage to household furnishings. In this work, we sought to identify potential semiochemicals in the urine and feces of domestic cats that may modify cat scratching behavior. Sex differences among adult, intact cats were examined for volatile molecules in their urine (n = 7 females, 7 males) and feces (n = 8 females, 10 males) using gas chromatography-mass spectrometry (GC-MS). Males had seven times more 3-Mercapto-3-Methyl Butanol (MMB, p < 0.001) in the urine and 98% more butanoic acid (p = 0.02) in the feces than females. One mL of mineral oil without (i.e., control) or with MMB (0.1 µg/mL) and butanoic acid (100 µg/mL; i.e., treatment), which corresponds to the estimated biological amount in a single elimination from a male cat, were evaluated for their effectiveness in modifying the use of scratching devices by cats. Two identical cardboard standing scratchers, treated with either the control or the solution containing both semiochemicals delivered through a hanging cotton sock were placed side by side in a home/shelter environment. The preference test consisted of exposing individual cats (n = 28) to both scratchers for 20 min and recording the duration and frequency they interacted or scratched each scratcher. The semiochemical solution significantly decreased scratching time (21.19 ± 3.8 vs. 6.08 ± 3.8 s; p < 0.001) and interaction time (31.54 ± 5.9 vs. 12.90 ± 5.9 s; p = 0.0001) and tended to reduce scratching frequency (1.49 ± 0.3 vs. 0.82 ± 0.3 times; p = 0.07) compared with the control solution. The male-representative solution of MMB and butanoic acid was aversive to cats and might have future applications in protecting furniture from the destructive scratching or in modifying behavior of domestic cats.

Efficacy of the Feliway® Classic Diffuser in reducing undesirable scratching in cats: A randomised, triple-blind, placebo-controlled study

Scratching the environment is a natural behaviour that cats use for communication and physical maintenance purposes, however when it is carried out on household furniture it is considered unacceptable for some owners and even grounds for relinquishment of cats. The objective of this study was to investigate the efficacy of FELIWAY® Classic Diffuser in reducing undesirable scratching (scratching vertical surfaces indoors other than the scratching post) in cats. A 28 day, randomised, triple-blind, placebo-controlled study with a total of 1060 caregiver-cat dyads was conducted. The study contained two groups: the Pheromone Group consisted of caregivers who were given a pheromone diffuser (n = 546) and the Placebo Group consisted of caregivers who were given a placebo diffuser (n = 514). A questionnaire with three subsections was distributed online. The first section, completed by the respondents at day 0, inquired about the cats' daily routines, social and physical environments, behaviour, temperament, and emotional states. The second section filled on day 0, 7, 14, and 28, assessed the Frequency and the Intensity of the undesirable scratching problem and the effectiveness of the product. The last section, filled on the 28th day of the product application, related to the caregivers' opinions about the product and overall outcome. After 28 days the scratching Frequency reduced for 83.5% of the cats in the Pheromone Group and 68.5% for the Placebo Group (p<0.0001). The Intensity was significantly different between treatment groups at D7 (p = 0.0170), at D14 (p = 0.0189) and at D28 (p<0.001). The reduction of the Global Index Score, which was calculated by multiplying the Intensity with the Frequency, was significantly higher for the Pheromone Group (p<0.001). This study provides direct evidence that the use of FELIWAY® Classic diffuser significantly reduces the Frequency, Intensity and the Global Index Score of undesirable scratching.

2023 AAFP/IAAHPC feline hospice and palliative care guidelines

The '2023 AAFP/IAAHPC Feline Hospice and Palliative Care Guidelines' are authored by a Task Force of experts in feline hospice and palliative care convened by the American Association of Feline Practitioners and the International Association for Animal Hospice and Palliative Care. They emphasize the specialized communication skills and ethical considerations that are associated with feline hospice and palliative care, with references to other feline practice guidelines for a more complete discussion of specific diseases, feline pain management best practices and cat friendly interactions. A comprehensive, multi-step hospice consultation allows for tailoring the approach to both the cat and the family involved in the care. The consultation includes establishing 'budgets of care', a concept that greatly influences what can be done for the individual cat. The Guidelines acknowledge that each cat and caregiver will be different in this regard; and establishing what is reasonable, practical and ethical for the individual cat and caregiver is important. A further concept of the 'care unit' is introduced, which is extrapolated from human hospice and palliative care, and encourages and empowers the caregiver to become a part of the cat's care every step of the way. Ethical considerations include a decision-making framework. The importance of comfort care is emphasized, and the latest information available about how to assess the quality of a cat's life is reviewed. Emotional health is as equally important as physical health. Hence, it is fundamental to recognize that compromised physical health, with pain and/or illness, impairs emotional health. A limited discussion on euthanasia is included, referring to the AAFP's End of Life Educational Toolkit for recommendations to help the caregiver and the veterinary professional ensure a peaceful passing and transition - one that reflects the best interests of the individual cat and caregiver.

Controversial Topics in Animal Welfare in Latin America: A Focus on the Legislation Surrounding the Human-Companion Animal Relationship and Animals Used for Recreational Practices

Animal welfare is a societally relevant issue that is globally attracting increased attention. This is in addition to the importance placed on welfare for the animals themselves. However, the content and application of laws protecting animals' welfare vary across countries. In Latin America, there are a range of common practices or activities involving certain animal species, many of which are legal, that can impair an animal's quality of life. These include the performance of aesthetic surgical procedures; bull-, cock-, and dog fighting; and the existence of circuses that exhibit animals. The extent and impact of these practices being dependent on the socioeconomic, cultural, territorial, and regulatory landscape of each country. Particularly, Ibero-American regions face welfare challenges that might be influenced by traditions and relevant legal gaps. The objective of this article is to review controversial practices carried out in companion and entertainment animals in Latin America, with a focus on legal aspects, as well as the current efforts being made to address and incorporate global welfare standards into domestic and wild animal practice and regulation.

Unwanted Scratching Behavior in Cats: Influence of Management Strategies and Cat and Owner Characteristics

Despite scratching behavior in owned domestic cats being a self-motivated and natural behavior, it is commonly reported as a behavior problem by owners when it results in damage to household items. The objectives of this study were to use a cross-sectional survey targeting cat owners within the United States and Canada, to explore perspectives on cat scratching behavior and management strategies, as well as identify factors that influence the performance of inappropriate scratching behavior in the household. A total of 2465 cat owners participated in the survey and three mixed logistic regression models were generated to explore associations between (1) cat demographic factors, (2) provisions of enrichment, and (3) owner demographic and management factors with owner reports of problematic scratching. In this convenience sample, inappropriate scratching was reported by 58% of cat owners. Owner perspectives and management strategies aligned with current recommendations as they preferred to use appropriate surfaces (e.g., cat trees) and training to manage scratching as opposed to surrendering, euthanizing, or declawing. Logistic regression results found fewer reports of unwanted scratching behavior if owners provide enrichment (flat scratching surfaces (p = 0.037), sisal rope (p < 0.0001), and outdoor access (p = 0.01)), reward the use of appropriate scratching objects (p = 0.007), apply attractant to preferred items (p < 0.0001), restrict access to unwanted items (p < 0.0001), provide additional scratching posts (p < 0.0001), and if their cat is 7 years of age or older (p < 0.00001). Whereas if owners use verbal (p < 0.0001) or physical correction (p = 0.007) there were higher reports of unwanted scratching. Results suggest that damage to household items from scratching behavior is related to management strategies owners employ, and these findings can be used to support owner education in mitigation and prevention of inappropriate scratching.

Dealing With Stress in Cats: What Is New About the Olfactory Strategy?

Domestic cats are descended from solitary wild species and rely heavily on the olfaction system and chemical signals for daily activities. Cats kept as companion animals may experience stress due to a lack of predictability in their physical or social environment. The olfactory system is intimately connected to the brain regions controlling stress response, thus providing unique opportunities for olfactory strategies to modify stress and related behavioral problems in cats. However, the olfactory intervention of stress in cats has been mainly focused on several analog chemical signals and studies often provide inconsistent and non-replicable results. Supportive evidence in the literature for the potentially effective olfactory stimuli (e.g., cheek and mammary gland secretions, and plant attractants) in treating stress in cats was reviewed. Limitations with some of the work and critical considerations from studies with natural or negative results were discussed as well. Current findings sometimes constitute weak evidence of a reproducible effect of cat odor therapy for stress. The welfare application of an olfactory stimulus in stress alleviation requires a better understanding of its biological function in cats and the mechanisms at play, which may be achieved in future studies through methodological improvement (e.g., experiment pre-registration and appropriate control setting) and in-depth investigation with modern techniques that integrate multisource data. Contributions from individual and environmental differences should be considered for the stress response of a single cat and its sensitivity to olfactory manipulation. Olfactory strategies customized for specific contexts and individual cats can be more effective in improving the welfare of cats in various stressful conditions.

A Feline Semiochemical Composition Influences the Cat's Toileting Location Choice

Unwanted toileting is amongst the most undesirable behaviors in domestic cats and can lead to conflicts between cats and the communities they are living in. This study aimed to confirm the effect of a semiochemical composition, reconstituted volatile fraction derived from cat anal glands, on the elimination behavior of domestic cats. A total of 31 cats were tested individually, for 23 h, in a blinded randomized choice test, with two litter trays, one sprayed with the treatment and the other with the control. Parameters included elimination weight, urine only weight, the record of the elimination type and counting of urine spots and stools, exploration duration of each litter tray, and first and second choice of litter tray to eliminate. Across all parameters, cats urinated and defecated significantly less in the litter tray where the semiochemical composition was sprayed than in the litter tray where the control was sprayed (for example: elimination weight p < 0.0001; urine only weight p < 0.0001; exploration duration p < 0.0001, and first elimination choice p < 0.0001). These results demonstrate that a semiochemical composition-derived from cat anal glands significantly decreases elimination at the location where it is sprayed. Future research is warranted to explore the possibility to manage unwanted toileting using this semiochemical composition.

Influencing Elimination Location in the Domestic Cat: A Semiochemical Approach

Simple Summary

In the domestic cat, elimination at an inappropriate location is considered by cat owners and non-cat owners as an undesirable behaviour. The aim of the study was to assess the effects of a composition derived from cat anal glands on the elimination behaviour of domestic cats in a cattery setting. The study was conducted in four catteries housing 33 cats, using 37 litter trays. The data collection lasted two weeks, each litter tray receiving one treatment on the first week and the other treatment on the second week. The parameters studied included daily elimination (urine plus stools) weight, urine weight, stool weight, elimination type and urine/stool quantity scoring. Four out of the six parameters studied showed a treatment effect, consistently in favour of cats defecating significantly less in the litter trays sprayed with the treatment versus litter trays sprayed with the control. These results demonstrate that a composition originating from cat anal glands influences cats’ defecation location.

Abstract

In the domestic cat, elimination at an inappropriate location is considered by cat owners and non-cat owners as an undesirable behaviour. The aim of the study was to assess the effect of a semiochemical formulation, reconstituted volatile fraction of cat anal gland secretions on the elimination behaviour of domestic cats. The study was conducted in four catteries, which housed 33 cats, using 37 litter trays and followed a randomised crossover design using the litter tray as the experimental unit. The parameters studied included daily elimination (urine plus stools) weight, urine weight, stool weight, elimination type and urine/stool quantity scoring. The parameters were analysed using GLMM with SAS 9.4 software. Four out of the six parameters studied showed a treatment effect, consistently in favour of cats defecating significantly less in the litter trays sprayed with the treatment versus litter trays sprayed with the control (elimination weight p = 0.0199; elimination type p = 0.0251; stool weight p = 0.0005 and stool quantity p = 0.003). These results demonstrate that an intraspecific semiochemical message originating from cat anal glands influences cats’ defecation location.

Rescued Cats Prefer to Scratch Fabrics Commonly Used to Cover Upholstered Furniture

Preference responses of cats for scratching fabrics commonly used on furniture were evaluated during four consecutive days in three Non-Governmental Organizations (NGOs) that rescue companion animals. Cats were grouped and their choices were registered at a group level (no individual identification). Daily choices for chenille, suede, synthetic leather, or waterproof grosgrain fabrics were evaluated for the cats' groups. A preference for chenille and non-preference for synthetic leather and waterproof grosgrain was found, independent of the NGO. In conclusion, although not using chenille does not assure that cats stop scratching furniture - especially if no other option to scratch is available - synthetic leather and waterproof grosgrain seem to be less attractive fabrics for these animals. Further studies are needed to investigate whether these findings apply to cats in a home scenario, when just one or a few individuals are usually present and only one type of fabric covering furniture is commonly available. Although we did not investigate the effect of providing scratching posts for these animals, we recommend such posts are available in the environment as scratching behavior is important to cats.

Effects of Human Presence and Voice on the Behaviour of Shelter Dogs and Cats: A Preliminary Study

Simple Summary

Environmental enrichment is fundamental for the welfare of shelter animals. This study compared the behaviour of single-housed shelter dogs and cats while being read a book (using a prerecording) in the presence of an unfamiliar human (without direct physical contact) or in its absence. Behaviours such as scratching the door, gaze direction and location in relation to the audio source/human were observed for 10 min. When a human was present, dogs spent longer in their bed and looking at the auditory source, while cats scratched the door and rubbed against the door. In the absence of the human, cats tended to spend more time in the vertical dimension, where the hiding boxes were located. Overall, the presence of a person, combined with auditory enrichment, induced greater interest compared to just an audio stimulation in both shelter dogs and cats. However, some animals showed signs of frustration likely due to not being able to physically interact with the human. Given that dogs that exhibit calmness and cats that scratch the door in the presence of humans and try to attract human attention are more likely to be adopted, auditory enrichment combined with human presence promotes behaviours that may consequentially increase adoption rate.

Abstract

Reading books to shelter animals combining auditory enrichment with human presence is increasingly used although its effects on animal welfare have not yet been investigated. This study compared the behaviour of single-housed shelter dogs and cats during a prerecorded reading condition in the absence or presence of an unfamiliar human (without direct physical contact). Fourteen dogs and twenty-one cats were observed in their enclosure in the two conditions in a counterbalanced order. Behaviours such as scratching the door, gaze direction and location in relation to the audio source/human were analysed from video recording for 10 min per condition. Dogs spent more time in their bed (p < 0.047) and looking at the auditory source (p < 0.004) when a human was present. Cats showed door scratching and rubbing when a human was present (p < 0.043), whereas they tended to spend more time in the vertical dimension (p = 0.051), where the hiding boxes were located, during auditory stimulation without a human present. These results show that the presence of a human induces greater interest compared to just audio stimulation in shelter dogs and cats but may induce frustration likely due to not being able to physically interact in some animals.

The environmental needs of many Australian pet cats are not being met

OBJECTIVES

The aim of this study was to investigate whether Australian cat owners are effectively meeting their cats' environmental needs and to identify areas of deficiency that may have an impact on the cats' health and welfare.

METHODS

An online survey investigating lifestyle factors and provision of environmental resources was distributed to Australian cat owners.

RESULTS

In total, 12,010 respondents, representing cat-owning households, completed the survey. Altogether, 45.5% were single-cat households and 54.5% were multi-cat households, with a mean number of two cats per household. In total, 46.3% of households contained indoor cats, 51.8% contained indoor-outdoor cats and 1.8% had mostly outdoor cats. Dry food was the predominant food type in 59% of households and few respondents fed their cats in a manner that stimulates natural predatory behaviours. Altogether, 17.1% of households reported cats with urinary problems such as haematuria or urethral obstruction, and 19.8% reported inappropriate urination outside of the litter tray. The incidence of urinary problems was found to be significantly increased in multi-cat households, those with a low number of litter trays, less frequent cleaning of the trays of faeces and the use of crystal type litter. The veterinary clinic was the most common place to obtain advice about feeding and toileting management.

CONCLUSIONS AND RELEVANCE

An increased number of Australian households now contain multiple cats that live restricted or indoor lifestyles. Despite the majority of respondents claiming to have a lot of knowledge about cats and obtaining veterinary advice, deficiencies were identified in toileting facilities and feeding practices, which raises significant welfare concerns. Urinary tract disorders are an important cause of morbidity, mortality and relinquishment and its presence was associated with inadequate toileting facilities. Ongoing education of cat owners and an increased effort by veterinarians to include basic husbandry in preventative care consultations is critical to improving the welfare of pet cats.

Tools for Managing Feline Problem Behaviors: Pheromone therapy

PRACTICAL RELEVANCE

Cats are one of the most common companion animals in the world. However, relatively little scientific research has been conducted on cat behavior. With problem behaviors a leading reason for relinquishment of cats to shelters, or abandonment outdoors, solutions to address feline behavioral problems can have important welfare benefits. Because naturally occurring pheromones produce measurable species-specific responses in cats, the use of synthetic pheromone products consisting of the same compounds may activate a specific behavioral response in the receiving individual, allowing humans to better communicate with cats and manage feline problem behavior.

AIMS

In this article the scientific background for naturally occurring feline pheromones and semiochemicals and their impact on cat behavior is reviewed. This is used as a foundation to explore the three feline synthetic pheromones currently available and the empirical evidence that exists for their effectiveness. From this information, several recommendations for veterinarians and behavior professionals on the application of feline pheromone therapy in the home and veterinary clinic setting are presented.

EVIDENCE BASE

The efficacy of synthetic pheromones as a tool for the management of problem behaviors is a relatively new area of research and only fairly recently has the need to implement more rigorous research methodology been recognized.

Effect of l-theanine tablets in reducing stress-related emotional signs in cats: an open-label field study

Background

L-theanine is an aminoacid found in tea leaves which has relaxing effects in humans and animals. It is a structural analogue of glutamate which can bind glutamate receptors. Although the relaxing action of L-theanine has been shown in humans, laboratory animals and dogs, it has never been published in cats. The goal of this open-label, multicentre and prospective trial was to determine whether an L-theanine based oral supplement (Anxitane®, Virbac, France) could attenuate manifestations of stress in cats under field conditions.

Case presentation

Thirty-three privately owned cats presenting signs associated with stress or fear (inappropriate urination/defecation, fear-induced aggressiveness, hypervigilance/tenseness or physical/functional manifestations of stress) for at least 1 month, were included in the study. They were given L-theanine (Anxitane®, 25 mg twice a day) for 30 days and 20 stress-related parameters were scored at Days 0, 15 and 30. The evolution of some parameters was also rated relative to Day 0. All median scores of the 20 parameters were significantly reduced at D30, and 30/33 cats (91%) had a reduced global score at the end of the study, including 21/33 with ≥50% score reduction. The median (IQR) global scores went from 18 (13-23) at D0 to 11 (8-13) at D15 and 5 (3-12) at D30 (p < 0.0001; Friedman test; significant reduction starting from D15). All the stress-related signs were significantly improved compared to D0, according to the owners, especially inappropriate elimination. Tablet palatability was judged good or very good in 94% of cases with spontaneous intake by cats when given by hand or in food. Tolerance was satisfactory as well, and no side effects were reported, so that most owners (27/33; 82%) were satisfied with the product.

Conclusions

Despite the lack of a placebo group, it can be concluded that L-theanine (Anxitane®) helped to improve the undesirable manifestations of stress in cats in as soon as 15 days, though better results could be seen after 30 days of administration. These encouraging results show that L-theanine can help manage stress-related behaviour, but additional trials with a placebo group should be run to confirm this effect.

Preference of kittens for scratchers

OBJECTIVES

The objective of this study was to determine kitten preferences towards different scratchers and the effects of catnip and cat odor on kitten scratching behaviors.

METHODS

Two-choice preference tests were conducted to compare scratchers and preferred scratchers with or without additives (ie, catnip, catnip oil, cat hair) in six studies. Kittens (n = 40, <8 weeks old) had access to two scratchers on the floor of a simulated living room for 20 mins and interactions were video-recorded. The time each kitten spent scratching each scratcher was compared.

RESULTS

In study 1, the S-shaped cardboard was preferred over a hemp post with a toy on top, and no difference was observed in the other pairs of scratchers compared. In study 2, the S-shaped cardboard was preferred by kittens compared with a raised scratcher covered with window screen or with carpet, and no differences were observed between the latter two scratchers. In study 3, the scratcher covered with window screen set upright was preferred over the same scratcher laid horizontally on the floor. The S-shaped cardboard was preferred over the scratcher covered with bubble wrap. In study 4, kittens preferred the S-shaped cardboard over the scratchers covered with window screen or short-fiber carpet but not over the scratcher covered with long-fiber carpet. In study 5, the S-shaped cardboard was strongly preferred over the long cardboard and rectangular cardboard but not over the boat-shaped cardboard. In study 6, dried catnip plant, catnip oil spray or the hair from other cats did not alter the scratching behavior exhibited by the kittens vs the control S-shaped cardboard alone.

CONCLUSIONS AND RELEVANCE

The S-shaped cardboard scratcher was a preferred scratcher for kittens. Catnip or odor of other cats did not alter this behavior in kittens. S-shaped cardboard may be a preferred scratching device for kittens.

Assessing the impact of a regional UK feline neutering campaign

Neutering is key to feline population control. Neutering campaigns provide education and/or financial assistance to encourage neutering. This study assessed the impact of the Cats Protection East Midlands Neutering Campaign (CPEMNC) on the proportion and ages of cats neutered. The CPEMNC, comprising of an outreach programme and voucher-based subsidised neutering scheme, began in June 2014. A convenience sample of owners who had attended 12 regional veterinary practices to complete a cat vaccination course in June/July 2014, or to have their cat neutered in October 2014 (CAMPAIGN) were compared with an equivalent control period in 2013 (CONTROL). Data collected by postal questionnaire revealed that the proportion of cats neutered by six months of age was significantly higher and the age at neutering significantly lower in the CAMPAIGN (n=134) versus the CONTROL groups (n=100). Results of multivariable logistic regression indicated cats were significantly more likely to be neutered by six months of age if they were in the CAMPAIGN group (OR 2.44) and male (OR 2.17), compared with in the CONTROL group and female. Further work is needed to evaluate factors important for campaign success and to explore the effectiveness of campaigns within the wider community and across the UK.

Survey of cat owners on features of, and preventative measures for, feline scratching of inappropriate objects: a pilot study

Objectives

The objective of this study was to collect preliminary data on relevant features and preventative measures of feline inappropriate scratching. Preliminary data could then be used to inform future randomized controlled studies.

Methods

A paper questionnaire was distributed to 140 cat-owning clients of a small animal practice. The response rate was 82.9%. Questions related to features of inappropriate and designated items scratched, frequency of the behavior and how owners attempted to modify the behavior. The frequency of scratching was ranked and analyzed with repeated-measures models for differences between features of items. The effectiveness of techniques to modify scratching was analyzed with Student’s t-tests comparing frequencies of scratching between cats of survey participants who did and did not use specific techniques.

Results

Scratching of inappropriate items was reported for 83.9% of cats. Most cats (81.5%) scratched chairs or other furniture and 64.1% scratched carpet. The frequency of scratching inappropriate items was significantly influenced by type and material of the items scratched, with furniture and carpet, and fabric and carpet, respectively, being scratched most often. Most cats (76.1%) had a designated scratching item. The frequency of scratching designated items was significantly influenced by type, with cats using scratching posts and other items more often than scratch pads. Owners used a variety of punishment- and reward-based techniques to stop inappropriate scratching and encourage scratching of designated items; only one technique was found to have a significant effect, with the frequency of scratching designated items being significantly lower in cats that were placed near the item.

Conclusions and relevance

Furniture covered with fabric was an object frequently scratched. Fabric should be further investigated as a potential material to encourage desired scratching behavior. Scratch pads appeared less desired than scratching posts. Punishment was a common strategy to deter scratching but did not appear to influence the frequency of scratching.

Owner observations regarding cat scratching behavior: an internet-based survey

Objectives

This study was performed to examine aspects of the cat, environment and scratching post that might influence scratching behavior, in an effort to determine how inappropriate scratching behavior might be refocused on acceptable targets.

Methods

An internet survey, posted on several public websites, gathered details about scratching behavior, as described by owners in their home environments, from 4331 respondents over a 4 month period. Responses from 39 different countries were analyzed, mostly from the USA, Canada and the UK.

Results

Owners offered traditionally recommended scratching substrates including rope, cardboard, carpet and wood. Rope was most frequently used when offered, although carpet was offered most commonly. Most owners provided at least one scratching post; cats scratched the preferred substrate more often when the post was a simple upright type or a cat tree with two or more levels and at least 3 ft high. Narrower posts (base width ⩽3 ft) were used more often than wider posts (base width ⩾5 ft). Intact or neutered cats (males and females) were as likely to scratch inappropriately, and inappropriate scratching decreased with age. Geriatric cats between the ages of 10 and 14 years preferred carpet substrate most frequently; all other ages preferred rope first. Inappropriate scratching decreased as the different types/styles of posts increased in the home. Inappropriate scratching did not increase if the number of cats or dogs increased in the household. Declawed cats were preventatively declawed most often to prevent household item destruction.

Conclusions and relevance

Although cats can have individual preferences, our data provide a starting point for veterinarians recommending scratching posts to clients.
