Brooks Kingsnake strange digestion and behavior? (diarrhea and biting himself)

[Bogertophis]

I use a DHP for my carpet python. It's mounted so the heat lamp housing is about 10 inches above the plexiglass top of his enclosure. The IR radiation penetrates the plexi rather well, so it heats up his driftwood "jungle gym" under it quite nicely. Being a semi-arboreal critter, he likes to perch there while digesting, and the heat that radiates from the driftwood helps with the ambient temp in the enclosure. I think CHE's work the same way.

Thanks. I suspect my spotted python (& some others) would enjoy the DHP- I may have to try one.
