Cat behavior can look very different across homes, climates, ages, and survey settings. Research from Japan, Tehran, Sweden, Italy, Australia, and the United States reports frequent concerns such as fear, aggression, scratching, inappropriate elimination, vocalization, and separation-related signs. These figures describe particular study populations and owner reports, so they are useful for context rather than as a universal diagnosis for every cat.

How common are reported behavior problems?
The prevalence of reported behavior problems varies sharply by location and study design. In a Japanese survey, 75.7% of cats were reported to show at least one of 17 behavioral problems. The same result was reported as 1,041 of 1,376 valid responses in Prevalence of 17 feline behavioral problems and relevant factors of each behavior in Japan. Because the percentage and count describe the same survey result, they should not be added together.
The Tehran clinic survey reported an even higher figure: 94.6% of cats had at least one behavioral problem in A survey of feline behavioral problems in Tehran. Cats in that survey had a mean of 2.71 behavioral problems, while the median was 2. The mean being higher than the median indicates that some cats had several reported problems, although the study figures do not establish why.
Owner responses also show that recognizing a problem does not always lead to an intervention. Only 11.4% of owners in the Tehran survey tried to take action to solve their cat’s behavioral problem. That figure measures reported owner action in that survey; it does not show that the remaining owners were indifferent or that no other help was sought.
These studies should be read as separate snapshots. A clinic population in Tehran, a Japanese survey population, and cats assessed under other circumstances may differ in age, health, housing, recruitment, and the way a behavior was defined. Their percentages are therefore not a global prevalence estimate.
Which behaviors appear most often?
The Tehran survey provides a detailed view of individual reported behaviors. Fearfulness was reported for 45.5% of cats, making it the most common listed behavior in that set. Attention seeking was reported for 37.1%. Aggression toward other cats affected 32.9%, while aggression toward people affected 31.7%.
Two household problems each appeared in 30.5% of cats: scratching inappropriate objects and inappropriate elimination. Vocalization in the owner’s absence was reported for 15.0%. These percentages describe the Tehran survey and should not be treated as mutually exclusive categories. A single cat could have more than one behavior, consistent with the survey’s mean of 2.71 problems.
The Japanese study used a different set of observations. Pica was one of the two most frequently reported behavioral problems, while showing fear on the examination table was the other. The supplied findings identify these as the leading pair in that survey but do not provide their individual percentages. They still point to two distinct contexts: a potentially harmful eating-related behavior at home and fear observed during handling or examination.
| Reported behavior or measure | Result | Study setting |
|---|---|---|
| At least one behavioral problem | 75.7% | Japan survey |
| At least one behavioral problem | 94.6% | Tehran clinic survey |
| Fearfulness | 45.5% | Tehran clinic survey |
| Attention seeking | 37.1% | Tehran clinic survey |
| Aggression toward other cats | 32.9% | Tehran clinic survey |
| Aggression toward people | 31.7% | Tehran clinic survey |
| Inappropriate scratching | 30.5% | Tehran clinic survey |
| Inappropriate elimination | 30.5% | Tehran clinic survey |
| Vocalization during owner’s absence | 15.0% | Tehran clinic survey |
Separation-related signs and vocalization
A separate questionnaire study focused on separation-related problems, or SRPs, rather than general behavior. In that study, 13.45% of cats met at least one SRP criterion. The result is not directly comparable with the 75.7% Japanese or 94.6% Tehran figures because the question was narrower and the criteria were specific to separation-related signs.
Among the cats classified with SRPs, 90.00% met criterion I, meaning the owner reported two or more SRP indicators. Criterion II was met by 70.00%; it required one behavior plus one or more emotional states. Criterion III was met by 16.67%, meaning the three mental states indicative of SRP were present. Half of the SRP cats met both criteria I and II, and 13.33% met all three criteria.
The most frequently reported SRP sign was depression during the owner’s absence. Excessive vocalization was the second most frequently reported sign. Agitation-anxiety and inappropriate elimination of urine were also common signs in that survey. These observations describe owner-reported patterns during separation and do not establish that every vocalization or litter-box problem has a separation-related cause.
Vocalization can also have several perceived causes in elderly cats with cognitive dysfunction syndrome. In the relevant owner survey, 40.5% said disorientation was the main cause of increased vocalization, and another 40.5% said attention seeking was the main cause. Food seeking was identified by 16.2%, while pain was identified by 2.7%. At the same time, 64.8% of owners believed there was more than one cause. The vocalization was rated at least moderately stressful by 40.5% of owners.
Scratching and owner responses
Unwanted scratching was reported by 58% of cat owners in Unwanted Scratching Behavior in Cats: Influence of Management Strategies and Cat and Owner Characteristics. The same study found fewer unwanted scratching reports among owners whose cats were aged 7 years or older. It also reported associations between fewer unwanted scratching reports and several management practices.
Fewer reports were associated with providing flat scratching surfaces, providing sisal rope, allowing outdoor access, rewarding use of appropriate scratching objects, applying attractant to preferred items, restricting access to unwanted items, and providing additional scratching posts. These are associations from the survey, not proof that any single practice will prevent scratching in every home.
The direction of the reported associations differed for correction methods. Verbal correction was associated with higher reports of unwanted scratching, as was physical correction. The findings do not quantify how often owners used each correction method or prove that correction caused the higher reports. They do show why a cat’s environment and the owner’s response are important parts of behavior research.
Outdoor access, housing, and relinquishment
The Swedish owner survey Owner Perceived Behavior in Cats and the Influence of Husbandry Practices, Housing and Owner Attitudes in Sweden reported three different patterns of outdoor access. Twenty-three percent of respondents said their cat was indoors only. Thirty-four percent reported free outdoor access, and 22% reported some form of outdoor access such as an enclosed area or leash walking. These categories reflect the reported survey responses and are not presented here as a complete accounting of every possible housing arrangement.
Many owners in that Swedish survey also said cats kept indoors only were more likely to be obese. This is an owner perception reported by the study, not a quantified obesity comparison.
Behavior can also appear in shelter records as a reason for relinquishment. In the 2018–2023 shelter records study Investigating the Reasons behind Companion Animal Relinquishment: A Systematic Content Analysis of Shelter Records for Cats and Dogs, behavior issues accounted for 28% of all relinquishment reasons. Housing and moving accounted for 18%, unable to care for 16%, too many pets for 10%, financial reasons for 6%, and owner allergies for 5%.
Within the behavioral reasons, aggression made up 32%, social conflict 28%, and soiling 13%. These percentages describe the composition of recorded reasons, not the percentage of all cats that displayed those behaviors. Shelter records can also reflect more than one circumstance surrounding a relinquishment, depending on how records were coded.
Fear, weather, examinations, and aging
In an Italian study of intense weather events, 91.1% of owners considered their cat’s sleeping behavior normal. Even so, 76.4% said sleeping increased when temperatures dropped, and 77.2% said sleeping increased during excessive heat. The survey also reported that 37.1% of cats never showed aggression toward owners, while 25.3% of owners reported inter-cat aggression.
Loud environmental stimuli were another important fear context. Sixty percent of cats were afraid of loud noises, gunshots, and thunderstorms. However, 31.9% showed no behavioral reaction to those stimuli. These findings come from owner-reported data and do not mean that a cat has one fixed response to every loud sound.
Examinations can produce their own behavior signals. In A New, Easy-to-Learn, Fear-Free Method to Stop Purring During Cardiac Auscultation in Cats, 8.8% of 582 cats were purring during physical examination, equivalent to 51 cats in the same study. The purring-stopping method succeeded in 89% of cases. The figures concern purring during examination and the performance of that method; they do not measure purring in ordinary home settings.
What owners want to learn
The US survey Socialising kitties: A quantitative survey of US cat owner attitudes towards kitten and adult cat socialisation programmes found that 69.3% of cat owners had not heard of kitten socialization programs. Even so, 50.4% said they would be interested in enrolling in a future program.
Owners placed high value on practical education. Education about reducing problem behaviors was identified as important by 87.0%. Understanding cat body language was important to 85.8%, and getting kittens used to handling was important to 83.1%. Together, these responses show strong interest in recognizing behavior and building handling skills, even though awareness of formal socialization programs was limited in that survey.
Environmental routines also varied in the Australian survey The environmental needs of many Australian pet cats are not being met. Indoor-only cats accounted for 46.3% of respondents. Dry food was the main diet for 59.0%, while wet food was the main diet for 28.0%.
Taken together, these statistics describe behavior as a combination of cat responses, living conditions, owner observations, and management choices. The most useful comparison is not a single universal percentage, but the specific setting behind each measure: clinic behavior, household behavior, separation signs, shelter records, weather responses, examination responses, or owner attitudes toward socialization.
