Fat Lip Syndrome

[Ceefa2]

Just got back from the vets as thought one of my cats had swollen gums at the front of her mouth - when her mouth was closed it looked like a bit of her bottom gum was poking out.

Turns out it's 'Fat Lip Syndrome' caused by an allergy. The vet was asking if I'd used any different sprays or anything I could think of that's different - no.

They've not given me any medication as they said it usually goes away by itself.

Has anyone else's cat ever had this and did it go away of its own accord? She's absolutely fine in herself.

Yes my cat has had it many times. It goes on its own but looks alarming. Shes the only one of the 6 I've had over the years with it.

Oh my goodness I'm so pleased you posted - my cat has got this and I had drawn a blank on google this evening!

My cat gets this from time to time. We've never been to pin down what he's allergic too but it doesn't seem to bother him

Thanks for the responses, they're reassuring. This is a photo of what her lip looks like at the moment:

Do you use plastic bowls for feeding? One of my cats had this a lot, but then read somewhere on Vet Google to change to stainless steel. It worked a treat and (touch wood) she seems to be a lot better.

Yes I do use plastic bowls. Not read about using stainless steel instead, that's certainly something to consider, thank you. Her 'fat lip' went away by itself after about 3/4 days after going to the vet.

One of our cats gets this OP, it seems to have reduced in frequency over the years too. Have never found out what triggers it and it never seems to impact on or upset him

It's called a rodent ulcer or indolent ulcer. Often associated with allergies especially flea allergies

The vet checked for fleas - combed all her fur and did the 'wet tissue' check - none found. Going to change to stainless steel bowls as just cannot think of what else could have caused it.

One of mine has had it three times this year,fine in herself.gets better in 3-4 days no intervention needed.had it at last check up/jab.vet said not a major problem if she's not in any discomfort/eating ok. Said it can be caused by a blocked sebaceous(sp?) Duct but usually rights within few days and doesn't require treatment
Think I may try the tip for stainless steel bowls,she's tiny and has a white chin so it's very pronounced on her!

Our old girl has it - partly stress, partly flea allergy, even thought she never has fleas

Advocate always works wonders.
