Thanks. I'm using small rats from a local shop and have been feeding him one per week.
I will not go to one every other week like the vet suggested. That's just too much of a switch, maybe every 9 days and see how he does.
I did put the cool hide in and replaced the warm hide with the humid hide.
Now he's in the cool hide all of the time.
Problem is he's so big that I cant fit all three hides in the enclosure, plus the water dish plus the log in a 30 long.
