I admit that it is probably no big deal when ingested as I said in my first post...It is just my experience that the snakes don't care for it in their mouths and would spit out the food item more frequently than I cared to deal with...
I loved the way it looked and the relative ease of cleaning when used as a substrate..Yes, the animals loved to burrow in it, but there are plenty of other options...
Use a separate feeding enclosure and you'll have no problems...
Getting rodents thawed without getting them damp is a skill I have never been able to master!!!
I gave up separate feeding enclosures long ago because it was taking up too much space...With 25 or so of these beasts to feed, it was also a time and work issue!! They don't quite go into a feeding cage with same ease as a kingsnake or boa! Try putting a 7 or 8 footer in a feeding cage a few times...They are just too strong and fast...I was always closing the lid on some portion of their anatomy...I just tap them with a hook when I'm picking them up for cleaning or a visit and I rarely have to dodge!!!
