I think my cat is having an allergic reaction to the bag of cat nip he ate. I came home yesterday to find him laying in the middle of the floor covered head to toe in cat nip. The kitchen was coated in the stuff too. He did get sick last night. When I got home today from work today I noticed that he has a bald spot on his face (I think from scratching) and the skin around his eyes is very pink/red. He is licking and scratching him self everywhere non-stop! Has anyone ever heard of a cat being allergic to catnip before?
