Has anyone ever heard of a cat having a cold or allergies?? If so, how do you know the difference and what can you do about it? I am asking this about my sister's cat, Puddin. She says that when she moves, she wheezes, or when you move her, she wheezes and she is sneezing every time she wakes up. She has been sleeping normal....but her eyes look really droopy...you know like you know she doesn't feel too good. If anyone can help, please let me know! Thanks!
