Well, Lilith, as I have named her, has taken well to F/T mice, eating and pooping well, and not being nippy at all. She seems to be acclimating nicely. However, Saturday, when I went to feed her, I was pretty sure I saw small lumps. Because she was contorted trying to 'kill' her mouse, I was hoping maybe it was just an effect of her color pattern, contortion and lighting. I let her be for a few days, and took her out for a closer look today. She most assuredly has lumps. The lumps are small (~2-4 mm) and directly under the skin. There are at least 4 of them, all on her sides (None on her back or her belly) they are all firm, but don't seem to be connected to the underlying muscle. When I was feeling them, they seem to slide and give with the skin. Her eating, & defecation, etc are all totally normal, in fact, robust (she eats like a champ, and poos like one too. I will have no problem getting a fecal for the vet) She is active at night, exploring her enclosure, and when handled, is generally very inquisitive, shows no signs of distress or agitation at all, both inside her enclosure, or during handling. Already have a Vet appointment for Saturday morning. In the meantime, I am hoping to read until my eyes are bleeding on what it might be, so I can be prepared (possibly) for what to expect. In my research so far, I have seen 2 things which seem possible. First (and most likely, I think) is that she has some kind of Filarial Worm encysted just under her skin. It is a common problem in W.C. snakes, and since I do not know her origins, it is possible. Treatment ranges from just de-wormers to actually having to surgically remove larger worms. Second (And less likely, but more dire) would be some kind of tumor. Some tumors can be operated with success. Others regenerate, and snakes don't exactly have a great record with Chemotherapy and other treatments. If anyone has seen or experienced anything, I'm trying to find out as much as I can about what it might be, and what I can expect.
