Inter-cat aggression is a common welfare problem in multi-cat households, causing chronic stress for all involved animals.
Inter-cat aggression represents a persistent welfare problem that is often underrecognised by owners because much feline aggression is subtle — avoidance, tense body postures, and resource blocking rather than overt fighting. Cats in conflict cannot adequately rest, eat, or use litter trays without anxiety. Welfare-centred multi-cat management starts with proper introduction protocols — gradual scent introduction before visual access before full contact — and continues with providing sufficient resources to eliminate competition. Where serious aggression exists, permanent separation with careful management of shared spaces, or rehoming one cat, may be the most welfare-positive outcome.
