I have used several beddings for my ball pythons. My favorite bedding when I was paying for it was shredded paper I simply got a shredder and shredded junk mail and stuff works great cheap and if they ingest it, it digest and passes. Now I work for a reptile breeding facility, and my bosses pay for my bedding as a perk for having me around lol.. I now use shredded aspen and like it alot but those are deffinatly my 2 favorite I also like cypress mulch but not as well as the aspen.. I would not recommend the shredded cocoa nut it sticks in the receptive heat pits, I would not recommend the large chunk bedding like repti bark.
