Inter-Cat Aggression - Why Cats Fight and How to Help

Why Are My Cats Fighting?

Conflict between cats in the same household can range from tension and avoidance to chasing and physical fights. These situations are often stressful for both cats and owners.

Possible causes

Common reasons include:

  • competition for resources
  • sudden changes in routine
  • redirected aggression
  • territory insecurity
  • poor introduction between cats

Even cats that previously lived peacefully together can develop conflict if stress levels increase.

Things that may help

Some adjustments that can reduce tension include:

  • increasing vertical space and resting areas
  • providing multiple feeding and litter areas
  • structured play sessions to release energy
  • temporarily separating cats during periods of escalation

When behaviour support helps

Inter-cat aggression often requires careful environmental adjustments and gradual behaviour plans.

If your cats are fighting or living with ongoing tension, behaviour consultation can help identify the cause and develop a structured plan.
