Hi, Im a first time ball python owner and Im concerned because this is new to me. My BP is about 4 years old now, and he always eats other than the occasional fast for 1-2 months. anyways, i tried to feed today, and he hasnt eaten for nearly 3 months now. I try usually every other week during a fast period and once a week when not. These marks appeared under his mouth and I have no idea what they are, if someone could help before i take him to the vet that'd be great. Thank you!
