If a cat develops upper respiratory infection, can it be transmitted to other cats?

Vivian: If a cat develops upper respiratory infection, can it be transmitted to other cats?
We have like 3 or 4 generations of wild cats outside. Two of them began to sneeze and had watery eyes. They would still eat and drink water, and seemed to be getting better when suddenly the mother cat and another sibling had the symptoms. Now just today, the uncle came around and he’s got it. If this is respiratory infection, can it be passed from one cat to another?

You consult a vet

Answer by Nan’s cat Tigger
Apparently it can, it’s probably a virus. If you care about them get them to a vet, but of course you will have to get them all treated for it to do any good.
