Hi everyone. I have a cat named Loco. He is an indoor/outdoor cat. He's about 3 years old. He's never had any health problems before. Lately, I think he's been very itchy. I THINK that's what it is. He'll be laying down, as he always does, then out of nowhere he'll start licking himself pretty violently. He then runs crazily aroud the house, licking himself. It's so bad, he jumps onto tables and knocks everything down. I've spent house google-searching this and just can't figure out what could be wrong. He definetly does not have fleas. I've looked in his fur with a microscope and didn't see anything. Not even a little dandruff or dry skin. Plus I have 3 other animals in the house, and none of them are showing any symptoms. He has an extremely healthy coat, very shiny and clean. He does shed somewhat heavily, but nothing I'd consider excessive or hair loss. No red spots or bumps either. So that seems to rule out allergies, bugs of any kind, and dry skin. I'm really at a loss here, I just don't know what else it could be. I feel so bad for him, whatever this is seems to bother him quite frequently. Thanks for any help you can give, I really appreciate it!
