Canker sore like lesion at my cat's lips
by TabbyGarfield, Nov 16, 2007
My 1 year old cat develops canker sore like lesion at the lips.  I have taken him to the vet 3 times.  The vet said he has allergy.  He had received 3 cortisone shots with no improvement.  Has anybody had similar problem with his/her cat?  Any suggestions how should I treat this condition.  By the way, my cat has no symptoms.  He seems to be playful and has good appetite.  Any help would be appreciated.

You might want to try a different vet. This vet sounds like he's just trying to run a bill up. Lesions can be a couple of different things, right up to signs of cancer. Sorry I can't be specific, but if the shot didn't help, they'd probably have to take a cell sample and test it.

My 1 year old cat also developed mouth sores.  She also had no symptoms except for the sores.  The vet was certain it was an allergy, and thought it may be to food.  She had a severe case and was given prednisone and was always on antiobiotics because her sores would become infected.  My vet referred her to the University of Florida School of Veterinary Medicine for a expert diagnosis and they said it was flea allergies.  Well guess what?? Wrong!!  She did not get any better after all but firebombing the house to get rid of every last flea.  After trying many different kids of foods (dry and canned) I discovered that when she eats only Royal Canin limited ingredient dry food, she has no more mouth sores!!  After almost $1,000 in vet and exterminator bills, I am so happy that she is well now.  

I hope this helps!!

Yes, pet allergies do suck. They're a pain in the butt to figure out. It takes a lot of work and can take months to narrow it down but it is possible.

My female 8 mo old has recently came down with mouth sores.  I will definately try the Royal Canin.  A daughter of mine has the same thing caused by yeast so I wonder if the Royal Canin maybe doesn't have glutton in it.

PLEASE don't put neosporin on your cat's lip, that might be poisonous for your cat to ingest.  I would take the cat to the vet, it sounds like an abscess that needs antibiotics.

my 3 yr old had an enlarged yellow lower lip the first 2 vet visit were the same antibiotics
steroids and a very large bill w/no relief for my pet he began to sound like he was having a hard time eating and drinking so i went to another vet she opened his mouth causing his to to pretrude and down his throat on the far bck side of his tongue was a growth she was sure it was cancerous so it had to be removed his lip began to clear a little but never really healed completely.  At one point it was thought to be feline herpes. I dont know if any of this helps or scares you but you may need to see another vet,

A neighbor's barn cat recently passed away. The symptoms happened w/i days. She stopped eating (I was feeding her daily) early in the week, and w/in 2 days, she had developed sores and was not doing well. My neighbor took her to the vet the following day, and I was told that the cat's kidneys (both) were as hard as a rock and the cat had a bad odor as well. The vet euthanized her, believing that she was too far gone and possibly may have had cancer. It just seems bizzare to me, as the onset was so sudden and devastating.
I know the neighbor has rats by the barn. Would it be possible that the cat could have been bitten and that an infection developed?
