I guess yours likes a clean house? Hahaha. Snakes aren't all the same- you'll just have to pay close attention to yours, as to what they like & respond best to. And when you try fresh-killed, make sure he's HUNGRY- by that, I mean a bit longer interval since the last meal, & make sure he's not going into shed. Most take it quick, but there's exceptions. (If they were kids, they'd be refusing to eat their veggies... ) Can't guarantee you won't need to re-heat. Besides, I hate to spoil any "surprises"-
