Okay, thank you!
Yeah, by the time our nights get problematic he will have a better setup (right now he's probably fine because I have a heat lamp that I have raised so it doesn't melt the plastic, but it was kind of done on the fly and isn't what I'd want for long-term). For now although outside the temperature dips a bit, the indoor temperature is still in the good zone. Winter will not be so kind.
I'm thinking he is pretty underfed from both Petsmart and his previous owners. He seemed a bit underweight when I got him, but he looks better now.
I'm going to try and transition him to rats when I get a bulk order of them. I'm getting a Brazilian Rainbow Boa who is already eating rats, so I'm going to order both mice and rats in bulk so I still have him covered with mice if he doesn't take rats at all, but hopefully I can transition him. I'll have to make sure the site I'd order them from have a small enough size - I'm not sure the range they do for rats, but I think adult mice might be just a tad too large for him, though hoppers are probably too small. He is at this between stage, I guess.
Yeah, I try to feed him towards evening or leave it overnight in case he is too shy. I'm going to try and feed him again tomorrow night after I scrub his bin really well as I've read that can help with tricky feeders. I'm not sure if he is really being tricky, or he is just still unused to a new schedule or something. His previous owners were really vague on how often they fed him, do this may be more than he is used to or something.
