Help he couldnt eat it!!!!!!!!

the width of the prey item that you feed should be slightly smaller than the girth of your snake at its widest point. that said, they can take down a larger meal, but it is not recommended. so unless this mouse was just huge in comparison to your snake's girth the problem likely wasn't that he couldn't get it down.

if the mouse wasn't warm enough he may not have been able to figure out where the head was in order to start swallowing. i have one bp that i have to make sure strikes on the head of the rat (luckily he eats f/t so this is pretty easy), otherwise he just pokes and chews and messes around with the rat and doesn't ever eat it, as if he just can't figure out where the head is.

definitely get a digital thermostat/hygrometer. walmart sells an accurite brand one for about $15. are you using a thermostat to control your uth? that should help with your temperatures as well.

Then that could be part of it. A snake won't eat if it's too cold....he knows that when it's cold, he can't properly digest his meal (it can actually just rot in the gut), so he refuses to eat until the temps warm up, ...to the right temps, AND CONSISTANTLY. No need to (deliberately) drop the temps at night. If it's b/c there are bugs in your husbandry and it gets too cold at night, then those are fixable. :D :D
