My ATB won,t refuse a meal even if i overfed him. Such a wonderful snake. I have to be careful with his feeding as he is a great eater. He is 14 months old and eating large mice. I have learned my lesson with my BP when he stopped 8 months eating. I feed him now small rats. Regarding my Dumerils, i really don,t have to be careful with his feeding. If he is not hungry he will just refuse. I can,t overfeed him. And my BCI refused food this time, so i will give him 2 weeks pause. My GTP will eat one large mouce every 9 to 10 days. That,s more than enough for him as he does not move much.
