Pet's info: Cat | Domestic Mediumhair | Female | spayed | 1 year and 8 months old
We have 2 cats who we think have had FeCoV passed on from our other cat who developed FIP and had to put him to sleep. The two we currently have live a normal life and have always bene indoor cats. We're thinking of adopting another cat, possibly youngish, and are worried that they will passed on FeCoV and develop FIP as they will be younger and have a weaker immune system. Is it a good idea to introduce another cat.

It is very difficult to predict which cats will get FIP because not only do cats need to be infected with the coronavirus, the virus also needs to mutate and cause an abnormal immune response. While it’s more common in multi-cat households the disease often does not affect all cats so I wouldn’t worry too much about your other cat. It also typically affects younger cats so if you adopt an adult the risk would be much lower. In 4-5 months there shouldn’t be any coronavirus in the environment.
