Hi- I just adopted three kittens from my friend's cat who got pregnant unexpectedly. She wasn't spayed and got out so the father's aren't known but the mother is a younger cat who is in good health. The kittens were born healthy and I am about to set up an appt. with the vet so they can get their rabies shots and get dewormed and checked for fleas. Lately, however, I've noticed that they are sneezing a lot and sounding kind of congested when they purr. Maybe it's just me since I've never had pets before, and it might be normal, I just thought it would be worth asking about. I'm not sure if it's anything in particular I should be worried about.
