Fearfulness associates with problematic behaviors and poor socialization in cats

Problematic behavior is a remarkable welfare issue in cats (Felis catus), as it is one of the most common reasons for relinquishment. The probability of developing problematic behaviors is likely influenced by several variables, but these remain little studied. In this study, we examined the associations of fearfulness, aggression toward humans, and excessive grooming with nearly thirty variables in a survey dataset of over 3,200 cats. To identify the most important variables influencing these behaviors, we used generalized linear models. All behaviors were associated with each other suggesting comorbidity between problematic behav-iors. Breed and several environmental variables were also associated with behaviors. Poor socialization with humans and a history of being a rescue cat were associated with higher fearfulness, indicating that the proper socialization of kittens is beneficial for avoiding fear-related problematic behaviors. Overall, our study highlights the complexity of three problematic behaviors in cats.

Automated summary

Problematic behavior is a significant welfare issue in cats and a common reason for relinquishment. Fearfulness, aggression towards humans, and excessive grooming are comorbid with each other, and breed and environmental variables are associated with these behaviors. Poor socialization with humans and a history of being a rescue cat are linked to higher fearfulness.
