Help! Lump on cats lip!

[/VIDEO]Hey everyone, my cat Simon has a lump on his lower lip. There are no other lumps and he has never had anything like this before. It kinda looks like a pimple, red with a little white around the top

Looks like a rodent ulcer.  I have no experience with them, but you could search for it here on the site or someone will be along to help soon.

Since no one has come along with personal knowledge, here's a link of threads about rodent ulcers.  Plenty of reading with lots of suggestions and helps.  One thing I have heard of, is adding pure evening primrose oil to a kitty's wet food (about 10-12 drops) once daily to help with inflammation.

My Yue had something like that once.  The vet suggested she might be allergic to her food dish (though I can't remember if that was it or not), and then gave me medicine. Went away aright away and hasn't come back since.   No matter what it is though, I suggest taking your cat to the vet to find out for sure.  We can't diagnose through a photo.
