Cats are naturally semi-solitary animals, yet millions are kept in multi-cat households that may generate chronic social stress. Understanding feline social needs, resource requirements, and conflict management is essential for maintaining welfare in homes with multiple cats.
Cats in chronic social conflict with housemates experience persistent low-grade stress that activates the HPA axis and sympathetic nervous system. This chronic stress suppresses immune function, predisposes to feline idiopathic cystitis, and causes persistent anxiety. Owners often do not recognise subtle conflict — a cat that never uses the litter tray when another cat is near, or stops eating when a dominant cat is present, is suffering welfare deficits invisible to casual observation. Feliway MultiCat pheromone diffusers reduce conflict in some households. The most welfare-positive approach is careful matching of cat personalities before multi-cat household establishment and providing adequate spatial separation.
