In multi-cat households, it is necessary to keep the environment as healthy as possible to avoid exposure to infectious agents. Preventing overcrowding, stress, maintaining cats vaccinated, proper nutrition, good hygiene, and eradicating feline leukemia infections can all help to reduce the risk of FIP in a group of cats.
A small number of FIP vaccines are available on the market. However, these are very controversial and are suspected of presenting a risk of infection rather than a protection against it.
