Conflict between cats sharing a household is a common and often unrecognized welfare problem, with subtle tension causing chronic stress even when overt aggression is absent.
Multi-cat household conflict represents a widespread and underappreciated source of chronic stress affecting millions of cats. Unlike dogs, cats rarely form genuine social bonds with unrelated household companions, meaning most multi-cat households contain cats under some degree of social pressure. The chronic, low-grade stress of ongoing inter-cat tension predisposes affected cats to stress-related illness, behavioral problems, and reduced quality of life. Owner recognition of conflict is often limited to dramatic fights, missing the abundant evidence of chronic tension in daily cat interactions. Welfare improvement requires honest assessment of whether each cat in a household has adequate resources and retreat space.
