Feline Lip infection

[amberlc1979]

My cats lip is infected.  He's on his 2nd round of antibiotics but his lip appears to slowly be getting worse. Its not an open sore, it's inflamed with pus pockets. His gums and mouth are fine. Teeth are clean, no tartar.

this was probably misdiagnosed it sounds like it could be eosinophlic granuloma complex or rodent ulcer...I will attach a link that has a write up abt this and some photos to compare with. it is 'usually' due to an allergy...mainly to additives or grains in the food..are you feeding dry food? if so, get your kitty on some good brand wet food with NO grains, also if you are using plastic feeding dishes switch to metal or ceramic....check out the photos on the link and read through the write up and get back to us...

Forgot to ask my question, lol. Does anyone know what might be causing the infection?
