Companion Animal Welfare

Cat Aggression Between Cats and Management

Inter-cat aggression in multi-cat households causes chronic welfare harm through sustained stress even when overt fighting is absent.

Key Facts

Covert inter-cat aggression often involves resource blocking and intimidation without fighting
Cats in conflict show elevated urinary cortisol and reduced play behaviour
Resource distribution including separated feeding stations reduces competition-based aggression
Spatial management using vertical and horizontal space reduces social pressure
Anti-anxiety medication can reduce aggression baseline during behaviour modification

Welfare Considerations

Inter-cat aggression in multi-cat households is one of the most chronic and underrecognised welfare problems in companion animal keeping. Owners often normalise conflict or miss subtle aggression signs. Assessment by a certified feline behaviourist can resolve the majority of cases through environmental and social management.

What You Can Do

Have your multi-cat home assessed by a certified feline behaviourist if you suspect conflict
Provide at least one resource per cat plus one additional to prevent competition
Create vertical space and multiple hiding areas to give cats options to avoid each other
