my kitten Sugar is 3.5 months old. She has been sneezeing a lot this last week, and I don't know if it's allergies, (what types can cats have?) or if it's the changing climate... or if she's getting a cold. I try to keep my apartment between 70-72°. My wife and I take her in bed with us along with her sister Spice to keep them warm if she is getting a cold... any other ideas to try or advice before I go to the vet?
