What are some common cat allergies?

The most common cat allergy is a flea allergy. Even though your cat may be indoor-only, they can still have contact with fleas on clothes that you’ve worn outside, especially if you have a dog that goes outside. There are also food allergies, and then there are environmental allergies from exposure to dust mites, pollens, and other things like that.

Allergies play a large part in the overall well-being of your cat. Your cat may have asthma, so they may not even be able to breathe well if they come into contact with these allergies.
