Avoid stress and overcrowding. Keep cats in small, separate groups. Consider isolating kittens from a mother cat at weaning to avoid exposure to the virus. Don’t mix very young kittens with older kittens. If you can limit coronavirus exposure until 12-16 weeks of age, when the immune system is better developed, the likelihood of developing FIP may be lessened. Breeders should avoid matings between cats who have had close relatives that have died of FIP or who have produced kittens that developed FIP. Also follow accepted protocols for vaccinations and practice good husbandry to limit other infections. Clean and disinfect cages and litter boxes regularly. The corona virus is easily killed by bleach and other disinfectants.
