I have a pregnant cat due any time soon.About three days ago she started sneezing and had a runny nose.But her eyes and eating habits are normal and fine. The cat is sneezing more often and when she breaths you can hear her nose is all stuffed up. I normal wouldn't be concerned but since she is pregnant I am starting to worry. Can her cold harm the kittens when they are born? Can the cold spread to the other cat in my home?
