The lump on the end of his tail ruptured like a week later. It leaked something, and shrunk like crazy. He seems fine. In fact, I think he's in less pain, but it certainly doesn't look pretty.
Was logged into twitter, made a normal post as usual, went to make another post, was suddenly not logged into twitter, went to login, it won't login, twitter hasn't said I'm banned/suspended. Annoying.
