Do you ever feed directly on Loose Substrate

[snakesRkewl]

Remember this one fact: Snakes digest rodent bones and fur. Do you really think a little piece of wood is going to affect them much?? I would say, only if it's really sharp and gets stuck somewhere, or if they take in a whole mouthful of it.

Always use aspen bedding, always feed on it with no issues. Once, one of my BPs got a piece stuck in their mouth, but they worked it out on their own before I could even open the cage door.

I stopped using aspen long ago, not because of digesting a few pieces, but because pulling it out of the throat of a large adult female ball python that is freaking out is no fun ...
I'm sure it's rare but...
