My vet said my cat has big lip, what is this

[carolbcac]

What exactly does the lip look like? There is a similar thread on here dealing with a cat with a swollen lip.

He may be referring to a condition that is called a "rodent ulcer" or an "indolent ulcer" which is often part of an allergic complex. Call the vet back and ask him (or the technician) what he meant. Vets sometimes forget that people out in the "real world" don't hear these terms on a daily basis!
