I tried to feed him a wingling mouse, frozen thawed but he didnt take. Im hoping that he will eat frozen thawed and not only eat live since he is from Africa and has complete wild genes in him.
CBB does not guarantee that a snake will eat F/T either if that makes you feel better.

Ideally you want to offer the same type prey that was offered previously most likely live, and if the animal was not started starting on live will be much easier for you.

The goal is to have your animal eat for first before even thinking about switching to F/T once he is consistent it will be a lot easier to switch.

And remember owning a snake means being willing to feed live, because not all of them will eat F/T
