Can you describe your setup? Maybe something husbandry related is making him not eat.

When you say you have a thermometer set to 92, do you have a thermometer or thermostat?

How are you measuring your temps?

Have you tried live? How have you tried to offer the f/t feeders?

I would try to get this guy eating regularly before giving up on him and letting him starve/getting another snake: and if you get another snake I would recommend a corn or king snake. I've had some slow starter ball pythons but after tweeking some things in the tub/trying other feeding methods they took to eating great.
