How long after the occurrence of FIP can I bring another cat into the household?

If you have lost a cat due to FIP, remove any cat-related items that you cannot wash or disinfect, such as scrapers or soft toys. Clean and disinfect everything else in the environment. Time will take care of the rest, because viruses of this type do not have a long lifespan in the environment. It is recommended for several months (about 2 months or more), which is the standard for most infectious diseases.
