I adopted a cat at the SPCA a month ago. He is about 5 months old. He sneezes a lot and3 days ago his breath started to smell verrrry bad. I do not know if the 2 are related. He eats Hill's Science Diet and Friskies canned food. Help!! :(

Did he sneeze from the moment you had him ? Probabley the fact that you adopted him, I'd say it was related, being that it was only a month ago ,sometimes these things take a while to come out,they may even pay for his medication.

Can you phone the spca and get some info'?. he could have cat flue and would need to see a vet as soon as possible,maybe get some anti-biotics.
