I agree with what everyone else has suggested as far as handling goes.
Does he have 2 hides in his enclosure, one on the warm side and one on the cool side?
And the half log things they usually sell at Petco/Petsmart are garbage!
Also, he should be eating something that is quite a bit bigger than a mouse fuzzy.
Probably atleast the size of a hopper mouse or rat fuzzy. Possible even bigger depending on how much he weighs.
