Multi-cat households present complex social welfare challenges as cats are naturally solitary and may experience chronic stress from inappropriate group living arrangements.
Chronic social stress in multi-cat households significantly compromises welfare for cats that cannot tolerate their housemates but have no option to leave the environment. Subordinate cats may live in a state of chronic anxiety, restricting their movements to avoid conflict, eating less than needed, and showing signs of chronic stress including hiding, reduced play, and stress-related illness. The link between social stress and idiopathic cystitis means poorly managed multi-cat households can cause painful physical illness. Owners often don't recognize the signs of inter-cat conflict, misinterpreting subtle avoidance and resource monopolization as normal behavior. Appropriate resource provision, environmental enrichment, and thoughtful household management substantially improve welfare for all cats.
