I was just about to say, we don't trust one of our syrians at all so we stapled mesh to the inside ends of her detolf
Then we made her lid carefully too so all she has access to is the glass or wire mesh. She can't chew through the mesh to get at the wood of the ends (or of the lid) so she's completely safe in there. The biggest issue we have is that she tries to push the lid off instead but we've found ways to keep it secure
Eggbiscuit (the ham in question) has to make do with chewing boxes and wooden things to shreds instead now, whether she likes it or not (and I dont think she does like it) she is definetly never going to chew out of her detolf
