Cat Welfare: Managing Feline Aggression Between Cats

Inter-cat aggression in multi-cat households is a major welfare problem causing chronic stress, injury and urinary disease, requiring structured management strategies.

Key Facts

Inter-cat aggression ranges from subtle intimidation to overt fighting with injury
Cats communicate territorial stress through blocking, staring and passive avoidance before escalating
Chronic inter-cat stress is a primary trigger for feline idiopathic cystitis (FIC)
Resource distribution - multiple locations for food, water, litter and rest - reduces competition-related aggression
Pheromone diffusers containing synthetic feline facial pheromone can reduce inter-cat tension

Welfare Considerations

Inter-cat aggression causes welfare harm to both the aggressor (who is chronically aroused and stressed) and the victim (who experiences fear, physical injury and stress-related illness). The management of feline inter-cat aggression requires understanding territorial behaviour and providing space, resources and management that allows cats to avoid each other when needed. Reintroduction after conflict using scent exchange protocols can rebuild tolerance.

What You Can Do

Provide multiple resource stations in locations that prevent resource guarding
Create escape routes and elevated spaces so cats can avoid conflict
Use FELIWAY Friends diffusers to reduce inter-cat tension
Consult a feline behaviourist if aggression is severe or causing physical injury
