My ball will constrict the thawed prey...funny thing is that he is not very good at finding an end to start eating. He has it by the body and tries to get it down...and can't...so he lets go and looks around for the head. Quite often he can't find the head (because it's under a part of him) and he lets go completely and goes back into his hide. If he does not eat it very soon after that, I take the mouse out and place it back into hot water and re-offer it to him.
He has constricted and then refused up to three times with the same mouse. If he's going to piss around then he can wait until next week...lol
If there is anything the nonconformist hates worse than a conformist, it's another nonconformist who doesn't conform to the prevailing standard of nonconformity.
