Cassy is FINE!!!

Sorry, I was so worried and this is such a relief. According to the vet he had a small cyst growing on one of his nipples (ouch). She was able to remove it non-invasively. It's all over. Whew.

I think it had shrunk since I found it (either that or my memory had built it bigger than it actually was) because I had to hold him down while the vet looked for it. (The vet tech couldn't find it and I was feeling pretty stupid holding Cassy between her leaving and the vet arriving...) Cassy-boy got a clean bill of health overall and I'm so relieved. The vet said there's no knowing what caused the cyst to form, but it isn't serious. [So I panicked for nothing. I guess that's a relief.

Thank you all for your thoughts and prayers. It helped a lot.
