A cat with FIP doesn't need to be isolated from your other cats. The coronavirus behind FIP is usually already present in multi-cat homes, and FIP itself develops inside the individual cat. Good litter hygiene reduces how much virus cats are exposed to.
- Provide one more litter tray than the number of cats, in different places and away from food and water.
- Scoop twice a day and fully clean trays weekly. Most household disinfectants inactivate the virus.
- Clumping, low-dust litter may help.
- Keep groups small (roughly three cats per room) and reduce stress where you can.
- The FIP vaccine is not recommended, and genetic tests for FIP resistance aren't reliable.
Ask your vet whether your other cats need any checks, especially if one becomes unwell.
