I just scanned that other "how do I get my BP eating F/T?" thread, but didn't want to hijack it, and also my situation's slightly different because my snake did eat thawed mice and rats consistently for a long time.

Our BP is probably a few months over 2 years old, we've had him right about 2 years now. For the first year and a half-ish he ate great. Frozen thawed only. Then going into this winter he went into a long fast that scared me a little. I've been all over this forum and other sites, I knew it's common, but it went on past winter into spring...I scrutinized my temps, hides, lighting, everything. Was careful to handle him rarely, even though when he was eating regularly he got handled more often and seemed fine with it.

Finally after maybe 4 months (winter's short in Tennessee) I got him to take an F/T rat, and thought everything was rosy again. The problem was, I couldn't get him to repeat it. That's the last one he's given a second glance to since November. I made sure his tank was clean, changed the bedding, tried leaving the food in his cage instead moving him to his old feeding container, checked his temps for the umpteenth time.... All these attempts were at night, too, I've always fed him at night since he was a baby. I tried the scenting the meal with gerbil bedding trick, with no luck. I was really hesitant to try anything live, fearing once he got one he'd never want to switch back. But eventually when he'd only taken that one rat in about 5 months, I gave in and bought a couple live mice.

He whammed the first one. I killed the second, thinking that freshly killed is at least closer to F/T than live, and a step in the right direction as well as being safer. He sniffed but wasn't buying. On a whim I decided to leave it in his cage overnight, and when I checked back 15 min later he had eaten it.

But that's the last time he's taken anything but live. I kept trying a live and an F/T, tried thawing the one in a little container with the live one to scent it, tried scenting the room beforehand with the live one to get him in the mood, tried everything. If it isn't moving of its own accord, he wants nothing to do with it. He looks almost embarrassed for me when I use tongs to "zombie walk" a dead one around. I've thrown away so many dead rodents in the last couple months, and am about ready to give in and resign myself to a snake addicted to the kill. But I thought I'd try you all just in case there's some hope, given that this same animal used to take thawed every time they were offered. Is there any way to flip the switch back?
