So just in case anyone was wondering why we're getting her lipoma removed, here's a couple of pictures of it. It's finally large enough that she preferentially lays on the other side. I would too if I had half a tennis ball under my ribs. It doesn't hurt when touched, but it's only a matter of time. So her pre-op appointment is in about 45 minutes, and we'll see what the doctor says. Hopefully we'll get a paws up!
Incidentally, it has been this size for a bit, but it has grown noticeably in the last couple of months. See this post.
