hi we have an exotic shorthair and since recently his upper lip is a bit swollen and red. what can it be?
He could have been bitten by a spider or another insect. Keep an eye on it and if it doesn't go down by tomorrow or gets worse, call the vet asap. He could also be allergic to something and be having a reaction.
That can be an infection or a virus also. Definitely take him to a vet if it doesn't get better soon.
your cat could of bit his lip. We have 2 exotic shorthairs and one of them did it today. I would still call your vet, though.
