Canker sore like lesion at my cat's lips

[TabbyGarfield]

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.

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?

Hi...that did develop really fast however if the kidneys were involved ie: cancerous thus not filtering as they should all types of sores can develop anywhere on the body.
A bite wouldn't cause the kidneys to become hard.
Hope this was of some help?

hi my 8 month old half persian cat also has sores on his lips and inside his mouth we went to the vet before and they prescribed a cream they said he had an infection we used the cream and it went but then shortly after it came back again so we went back to  the vets and they said it's cos his imune systems low he needs some more injections so they gave him 2 injections and prescribed for him another type of medicine which's bright violet and you put it on his sore and it stains the skin but that's not worked it's cost us nearly 150 euros and he's still not better it's spread and got worse so this monday we're taking him back to the vets and hopefully they'll take a sample or something and finally get rid of it forever when i find out more on monday i'll let you know what they say!!!

oh poor kitty, that must be very painful for him!!
I hope your vet can find out what it is, I hope he takes a biopsy of these sores to make a firm diagnosis.
One thing I would like you to suggest to him for an opinion is EOSINOPHLIC COMPLEX. you can look at this on the websites veterinarypartner.com or dermvets.com/feline_eosinopilic_granuloma.html   and see if the diagram looks similar to you.
this is a symptom of an allergic reaction to something, fleas/foods/dust or pollen
Similar to the allergies we humans get only in Pets the allergies show up on their skin where we sneeze of get stuffed up.
My cat has this disease and he gets small scabs on his skin and when he scratches or licks they break open and get raw and sore...he has an allergy to certain foods...we think and are in the process of trying different ones.
Antibiotics and steroid injections have only given short term relief.
I hope this will help you...let us know how you make out ok, good luck
