Desmond was not feeling well so my husband took him to the vet yesterday (in the snowstorm) and he has an URI. The vet gave him some antibiotics, so hopefully he will be feeling better soon.

I'm wondering if he possibly got it from Kiki, who we recently got from a shelter. Kiki does sneeze once and a while, but otherwise shows no symptoms. Should I take Kiki to the vet, too, or will she get over it on her own if she has one? The vet said the antibiotics don't treat the virus, just the bacterial infection that cats sometimes get. When we took her for her wellness visit after adopting her, they didn't say anything about an URI.

Last question- are cats who have already had an URI immune to it?

When we got Pippin from the shelter, he had an URI and was being treated with antibiotics. This was several years ago, but I want to know if I should keep the cats separated to minimize exposure.

Thanks! I know that was long-winded.
