Stacy -- Based on the vet's advice above, you should take your cat in to be examined.

My 12 year old cat Spirit has the same issue a swollen bottom lip. His had it for a few months now. I never took him to the vet, because he didn't seem to be in any pain. It would go down by itself so I assumed it was "feline acne" from what research I had done. Well it's back. It swells up and then gose down on its own. Now to add to this he has been excessivly grooming himself to the point on scabbing and hairloss.
Dose anyone know if this "rodent ulcer" could indeed cause excessive grooming and other skin irritations? I plan on taking him to the vet very soon but I what to get as much information as I can get before I send him into a bunch of testing.

Scott -- I'm so sorry. That sounds like a painful fall for your cat. What caused her to lose balance? Cats are very agile and this is unusual. Injuries such as these are one of the reasons we recommend cats be indoor-only. Your cat will be safe from such severe falls and from parasites and predators. Please consider this.

You should take your cat to the vet to examine this and to see if any other injuries were sustained. This article explains what happens to cats after falls on hard surfaces: LINK Good luck

My cat "face-planted" to the (street asphalted Earth)leaping/falling from the roof of my mid sized truck today. His bottom lip is swelling (just like a human/boxer's would from a fat lip). He is showing zero ailing signs; dizziness, extreme pain, aggressiveness, etc... just licking the area once in a while & it's obviously tender and sore. Do I just try to apply an iced/towell compress/pressure to it or do I need his normal vet to take a look/office visit ??. Thank You. SWS.

Linda -- Yes, it's true. An in-person examination from a vet is the only certain way to diagnose your cat and learn how to properly treat her affliction. If money is an issue, discuss that with your vet and see if the office offers low-cost or financing options. Good luck with Penny.

My cat Penny has had a swollen bottom lip on and off for several weeks, and I called Fallon Vet Clinic in Lunenburg, Ma and they said to try to give her baby benedryl, which I did several times. I was able to put some into her mouth, but then had to rub it on her lips. The swelling went down a little, but then popped up again. She eats well, acts normally, and it does not seem to bother her. The only thing that bothers me is that the vet cannot render an opinion without seeing my 2 year old kitten, which of course, I will have to pay for without including the medication for her. I have done my own research on the computer, and I think she needs some type of medication to get rid of this!

My male cat had this once, along with little bumps in other spots on his chin. After taking advice from the owner of a Healthy Pet Food Sore, I changed Bullet's food. He no longer eats anything with wheat gluten or corn products. The swollen lip and "acne" disappeared and has never returned.

i belive that it may be "feline eosinophilic granuloma complex" my cat has that and ill put a link to some pictures LINK if it looks simmlar or more "swollen" or "severe" then i would contact your local vet rather then go searching for a remedy your self

My 8 year old cat has recently developed this fat lip on the bottom lip. I think it is unlikely to be an eosinophilc reaction because my oldest (18 yo) cat had hard lesions on his chin about 10 years ago that he would scratch and then they would scab. A pharmacist I worked with who specialized in vet medicine told me this was a symptom of the eosinophilic reaction from allergy to plastic and ceramics. Since then I only use glass or metal bowls to feed my cats.

can i give my cat something from over the counter for his fat lip due to a allergy reaction to plastic?

My vet attributes my kitten's swollen and blistered lower lip to an airborne allergy. And as one might expect we have had no success figuring out what he is allergic to. His lip improves with a steriod injection followed by 5 days of steriod pills but within 5-7 days the lip is swollen and blistered again. Any one out there with similar problems and how it was treated? I'd love to hear from you.

Thank you for this information - it was very timely! I noticed my cat's upper lip looked a little swollen tonight. The article was very helpful and gave me a possible diagnosis until I can get an appointment with the vet. Thanks again!

Wow; how do cats catch this 'rodent lip'? More accurately, how do they NOT catch it? Is there a vaccine?
