Blister on Cats Lip (Updated with Pics)
When it rains, it pours. I'm still dealing with constipation issues with my female cat. Now today, I noticed my 7 year old male cat has a fairly large blister on his lower lip.
His behavior and activity are normal, and he's eating and drinking as normal. He has always been a water drinker/player. He loves to dip his paws in the water, and lick the water off his paws, stick his face under the faucet and drink from the bathroom faucet. So given he's constantly messing in water, and its always dribbling down his chin, he's always gotten small blisters here and there from the constant wetness on his chin. But this one looks different. Its rather large and pink with a sore in the center, appearing as if he has a fat lip.
I hate dragging him to the vet, because he has a huge fear of carriers, cars and vets after a traumatizing bad experience a year ago at a previous vet that cut him open unncessarily. But I don't want to take any chances. So I'm calling the vet to make an appointment to get it checked out to be on the safe side. But I was curious if anyone has any ideas on what this could be, and if its something I should be overly concerned about.
The only thing that I've changed, is his food about 3 weeks ago. I switched them from a non-healthy Fancy Feast Brand to Evo.
I guess I should also mention that he's strictly an indoor cat. It's very possible that my female cat smacked him in the mouth with her claws, because she is very aggressive with him, in which case I'd hate to stress him out with a vet visit if its just from being smacked in the face. So maybe I should wait a day or 2 to see if the swelling goes down. But I'm curious to hear if anyone else knows what causes "fat lips"/blisters on cats mouths.
