Cat aggression is among the most common reasons for relinquishment and euthanasia. Understanding the multiple types of feline aggression and their causes enables effective management that prevents harm and saves lives.
Cat aggression welfare harm is bidirectional - both the cat experiencing the emotional arousal that drives aggression and the human (or other animal) who is its target experience welfare harm. A cat who aggresses frequently is typically experiencing chronic fear, frustration, or pain that deserves treatment. Cats who are punished for aggression experience additional fear that worsens the problem. The welfare approach is to identify the type and trigger of aggression, address underlying causes including pain and resource competition, and modify the environment to prevent situations that trigger aggressive arousal. Relinquishment and euthanasia for manageable aggression represent welfare failures that early intervention can prevent. Understanding aggression as a welfare indicator rather than a behavior problem opens better treatment pathways.
