How to diagnose seasonal allergies in cats
Look for licking or chewing.
If your cat is licking or chewing its paws, abdomen, back, or legs, it could be simply engaging in regular cleaning and maintenance. However, if the licking produces excessive hairballs or exposes the skin, your cat is itchy.
This itchiness could be due to seasonal allergies. As a result of its licking or chewing, you might see open sores or wounds on your cat.
