Thanks for the concern. He has a 5.0 UV strip light and the substarte is crushed walnut shell. Crushed walnut shell is completely digestable and will not pose any risk to him. He never leaves the canopy of the tree anyway.
Crushed walnut shell is not digestible, it is merely small enough to pass through the digestive system without causing damage (usually). It will still cause an impaction if enough is ingested. Add that is organic and likely damp and can be a breeding ground for bacteria, molds, fungus and all manner of other pests and you've got a problem.
