I just got a new Pueblan milk snake 2 weeks ago, he is eating perfectly fine and everything, but when I put him back in his cage he just hides, he could go for a day without even moving. He rarely moves, unless I have to pick him up and feed him. I know their nocturnal, but when I go to sleep and wake up in the morning, he is still in the same place. Is this normal? Or is he just getting more comfortable with his new home?
