He's going to be fine. It turns out that is is that granuloma thingy. I tried to sound all intelligent to the vet and asked about that being quite common. He agreed and said that's what he thought it was originally (he is the kitty vet) but didn't like to say right away because there was two lumps that looked a bit suspicious. Aparently they had a case in the past where he told a woman what he thought it might be but the results came back much worse and she tried to sue them. But I'm just glad that Cleveland hasn't anything too serious wrong with him. Vet said he'll discuss next steps when Cleveland goes in to get stitches removed. I'm soo relieved.
