I have kept BPs for awhile, and just got my first bci a week ago. I fed him two mice a few days ago, because he appeared a bit thin when I got him. I can't believe the feeding response!
Another really good thing about this snake, is that he can differentiate between feeding time, and when I'm picking him up for handling. He smells that mouse, and WHAM! But when it's just my hand, he is inquisitive, and his neck is relaxed.
I am going to be switching him to baby rats soon. I read somewhere that you can feed them small rabbits when fully grown. Can you get away with just using large rats instead? (if not, I will use rabbits, just wonderin'.)
