I completely agree with Lija. My 2 year old male only eats once a week or so and won't touch crickets, only larger prey like dubias and hisser roaches and once a month a jumper mouse.
I can some times feed large Canadian nightcrawlers and hornworms.
He is already slowing down for the winter even though I use a zoomed htgrotherm controller to keep him at 81F at day and drop to 75F at night with a 12hr day.
I keep his enclosure at 70% RH. and he is doing fine.

I do take him out for a weekly soak in treated 80F water for 15 to 20 min with a bath towel over the container to give him some privacy and keep the warmth in.
He does all his business then and about 50% of the time sheds.

It keeps his enclosure very clean.
