Managing and Mitigating Aggression: Protocol for Dealing with Conflict Between Cohabiting Cats

  • When aggressive outbursts occur between familiar cats, distract them as soon as possible.
  • Never lift them up when they are behaviourally aroused as this might lead to redirected aggression, causing serious injuries.
  • Avoid using anything with a shrill noise as this can frighten and startle them which may compound the problem. Toys with bells rolled across the floor are ideal.
  • For mild altercations (hissing, spitting), it’s usual for cats to disperse to different locations. With a little time, most usually simmer without any real issues.
  • For a moderate altercation (hissing, spitting and swiping) separate the cats immediately, placing them in familiar locations with their own set of key resources.
  • Allow the cats to recover and calm down.
  • Synthetic pheromones containing the Cat Appeasing Pheromone have been shown to reduce cohabitation problems so using this in the environment may be helpful.
  • During this time caregivers should operate a time-sharing policy in the hub of the home as confinement for lengthy periods might trigger stress.
  • Before reintroductions, the cats must be showing signs of relaxation and freedom from stress.
  • Reintroduce the cats, following the steps in Introducing New Cats to a Home with a Resident Cat (https://petcourses.co.uk/free-resources/introducing-new-cats-to-a-home-with-a-resident-cats).
  • The aim is to proceed with gradual, positive introductions.
  • For repeated problems or more serious conflict (fighting) keep them separated and seek professional advice from a suitably qualified feline behaviourist.
