How to recognize and manage inter-cat tension in multi-cat households to protect the welfare of all resident cats.
Multi-cat household stress is a significant and underrecognized welfare problem. Because cats suppress pain and distress responses, covert tension between household cats often goes unidentified until a cat develops a stress-related health problem. Owners commonly interpret the absence of obvious fighting as evidence of harmonious cohabitation, when the reality may be that subordinate cats are chronically stressed through resource denial and social restriction. The welfare framework for multi-cat homes requires treating each cat as an individual with territorial needs, ensuring resource sufficiency and spatial separation as needed, and monitoring behavioral indicators of stress in all resident animals regularly.
