Introducing Cats or Cats Fighting? Help in Durham Region & Across Canada
Bringing a new cat home should be exciting, but when the cats you already have hiss, chase or fight, it can feel like a mistake. It isn’t. Most cats don’t become friends on day one, and tension between cats is very common, even between cats who used to get along. With the right plan, many households settle into a calmer routine.
Why “letting them work it out” often backfires
Letting cats sort it out face to face can lock in fear and fighting. Cats can’t leave a shared home the way they might outdoors, so a bad first meeting can set the tone for months. A gradual introduction lets each cat feel safe while getting used to the other.
What a good introduction looks like
Every household is different, but a gradual introduction usually includes:
- A separate, secure space for the new cat to settle in
- Swapping scents (bedding, blankets) before cats meet
- Short, calm, controlled meetings, with rewards for relaxed behaviour
- Enough litter boxes, food bowls, hiding spots and perches for everyone
- Moving at the pace of the more nervous cat, even if that takes weeks
When cats who used to get along start fighting
Sudden fighting between cats who were fine before can have a cause: a vet visit that left one cat smelling strange, something seen outside a window, a change in the home, or an illness. I always ask clients to have their vet check both cats first, since pain can change how a cat reacts to a housemate.
If a fight breaks out
Don’t reach in with your hands. Make a loud noise from a distance, or use a large piece of cardboard, a cushion or a blanket to block and separate them. Give both cats time apart in different rooms, and avoid punishing either one.
How I help
Every cat and home is different, so I don’t offer a one-size-fits-all fix. I will:
- Learn about each cat’s history, personality and your home’s layout
- Work out what’s driving the tension
- Build a step-by-step plan using positive reinforcement and changes to your space
- Support you as you put it into practice and adjust as the cats progress
I offer in-home visits in Durham Region and virtual sessions across Canada.
