A couple days ago my cat came in with a lump on his cheek (hes an outdoor cat and stayed out for the night this was the first we'd seen the lump). It was quite large about the size of half a ping pong ball and quite soft. We havent taken him to the vets as he's had no side effects of it. We know its nothing to do with the mouth or throat as he can eat perfectly and he isnt coughing/dribbling. I've researched and heard it could be a lipoma although it has been going down a little bit. Any suggestions on what it could be? It's not liquid filled, feels more like fatty tissue.
