I've noticed that the one female has had the one large lump for a while. I noticed others on this forum had similar issues and guessed that it was likely the tumor issue. It seems that just recently the tumors have gotten more severe. I watch her with a close eye now, and she doesn't seem to be in any pain. She doesn't clean/bite/etc the sores excessively.
Ideally, I'd like to feed her off, but if there's even a chance that it could mess with my snake's health (if ingested), I need to simply euthanize her.
