you checked for mites, sounds like your snake was being kept too warm. I agree with richsballpythons that many keepers are keeping their snakes too warm from what they read and not paying attention to what their snakes are doing. My hot side is in the mid to upper 80's and that might be too hot. I have notice that when my hot side gets into the low 90's most will head for the cold side of a cb 70 tub. if you do a lot of reading on these forums, you would of read that some of the breeders feel that durning breeding season even with the temp drop most do for breeding. these temps are still too high. some breeders are seeing better results with lower temps. (I'm not talking incubation temps but breeding temps.) if a snake eats, and digest it's food properly at lower temps, why 92 to 94? if your answer is R.I.then you need to not only read more, but pay more attention to how your snake react to what ever you do. what works for one, might not work as well for another. in this hobby reading is important, but there's much more to it than that.
