Is it safe to introduce an FIV negative cat to a vaccine-positive cat?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Female | spayed | 5 years and 6 months old | 10 lbs

My question is if we find out she in fact had the vaccine so she is testing positive, could you have a FIV negative cat with her without the same kind of risk as if she has the FIV infection naturally?

If Penelope is testing positive for FIV because she had the vaccine (and not the natural infection), then she does NOT actually have FIV. She is FIV negative in reality. So then getting another cat who is FIV negative is safe. Neither cat can spread FIV if they don't actually have the naturally occurring infection. Does that make sense?
