I have a female Brown Basilisk (her name is Luna). My parents have been keeping care of her for the last month and a half or so while I have been moving. She has been on a cricket and meal worm diet and gets plenty of exercise climbing and running on the couch. About a month ago a knot has appeared on her left rear leg, but she doesn't pay any mind to it and it doesn't seem to cause her problems. Any idea of what it could be?
