Pet's info: Cat | American Shorthair | Female | spayed | 1 year and 3 months old | 8 lbs
My sister had two cats (under a year.) One, unfortunately, died recently from the dry form of FIP. While the other cat was exposed, he’s not shown any symptoms of the fatal virus himself. My sister asked if we could watch her remaining cat while she’s away for a month (5 months from now.) While I’d love to, we have two cats of our own (18 months, and 2.5 years old.) Would her cat be able to transmit the virus to our cats? Could he be a “silent” carrier shedding the virus?

FIP is caused by a mutation of feline coronavirus and the disease itself is not contagious. Feline coronavirus is very contagious but in most cats will not cause symptoms or even will only cause mild diarrhea. Only 1-5% of cats with coronavirus will develop FIP. I think its fair to be cautious but the likelihood of your cat developing FIP is very low. If you prefer peace of mind then maybe consider helping your sister find another pet sitter.
