I wonder if this is OK for snakes - I have my hognose on it because when I bought the bark chips they had a strong smell of something so I took them back. I've been reading around the place and found a forum which advises always feeding snakes outside of their viv to avoid them accidentally ingesting the substrate (whatever it may be) as it could cause impaction. So I'm now a bit worried about this with the hemp (as it's loose) and also Emily (BP's) bark chip substrate. I think I might put some sheeting down around the feeding area in the viv when I feed them as I have noticed that the loose stuff does sometimes stick to the rodent.
