I bought my 2012 male in June. So far this has been his food schedule:
June 17th – 1 live mouse
June 24th – 1 live mouse
July 1st – 1 live mouse
July 8th – 1 small frozen rat refused
July 10th – 1 live mouse

I've been considering switching him to f/t. I tried it once and while he struck and coiled, he didn't eat. His last meal was on the 10th, yesterday I tried another f/t rat and the same thing happened. Struck and coiled, then lost interest. Today I bought a live small rat and he did the same thing, struck and coiled then started cruising around a feeding tub. He's been in there for about 45 minutes with the dead rat, he had zero problems killing it and the rat appears to be the proper size. It's the same size as his thickest part but significantly larger than the mice he had been eating. The reason he is in the tub is because I wasn't 100% sure if hed kill the rat and I didn't want to go fishing around his tub with his water/hides/him if I had to remove the rat.

I've seen on some websites that its okay to leave him in with the dead rat overnight to see if he changes his mind. Honestly, I could have been what spooked him, I put the lid on the feeding tub because I had to leave the room briefly but he was still coiled around it when I came back. Since its a feeding tub and not his actual tub, there is no hide or heating pad, just some holes and some clamps. Should I leave him for a couple hours? All night? Pull him out now?

I'm 99% sure he is hungry because the last few days hes been "looking for food" and as soon as he saw the rat he went right for it. My reasoning for wanting to switch to f/t is because its always been easier (and cheaper) for me to buy whole prey in bulk, if he decides he never wants f/t I am okay with it. I just don't know when to stop trying... I should probably give it more than one refusal before caving and giving him live but I don't like seeing him hungry, I know it's not damaging him, I'm just being a little sensitive girl about it hahaha. Anyway, thoughts/comments/suggestions are appreciated. Thanks.
