A 62 question survey was mailed to 375 individuals who adopted a cat from a local animal shelter. The goals of the survey were to identify the incidence of intercat aggression when a new cat was introduced into a household, identify potential risk factors associated with intercat aggression within a household and obtain various descriptive information on methods used to introduce a new cat into a home. The response rate was 72% (n = 252) with 128 of the households containing multiple cats and 124 of the households containing only the adopted cat. For this survey, fighting was defined as scratching and/or biting.
Among households with multiple cats, half reported fighting between cats when the new cat was introduced. Approximately half of the people introduced the cats into the home by simply putting the cats together immediately. Neither age, sex, nor number of cats in the household was associated with current fighting (i.e. fighting that was occurring 2?12 months after the new cat was brought into the household); however, current fighting was associated with individual behaviors (i.e. scratching and biting) during the cats first meeting, outdoor access, and the owner's perception of the first meeting as unfriendly or aggressive.
