I was given a California king snake and he has a problem with his mouth not closing on one side. I'm not sure if it's his jaw bone sticking through or something stuck in his gums but you can clearly see it and it's a little swollen around it. I don't have the $$ to see a vet because of Harvey. A have given him 3 f/t mice since I've had him and he ate them without a problem and I've seen him drinking. If it is something stuck I might try to remove it but I would hate to find out a was pulling on his jaw bone.
