Will my vaccinated cat get sick fostering a cat with Calicivirus?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 2 years old | 11 lbs

Hello, I noticed that my animal shelter is needing a foster for one of their cats, but she has Calicivirus. They want her out of the shelter for a while so she can relax and rest. I have a cat at home and he is up to date on his shots. If I were to foster her, would my cat get sick too? The shelter says she is on medication twice a day to treat it. Thanks

If your cat isn't vaccinated against Calicivirus, then yes Kovu can get it. Make sure his vaccines are up to date, and should reduce the symptoms should your cat acquire the virus from this foster cat. How lovely of you to want to take this foster cat in!
