Death to Aspen!!!

You should be able to get sizable pieces of broken roofing slate from a builders merchant, you just need to ask.

thanks for the tip - I'll try that

but my pieces are placed in loosely, so I can take them out and rinse all the soiling off. I also add some soft substrate like recycled paper animal bedding (like catlitter) in one corner on top, larger pellet types are best, so less risk of swallowing, as the snakeys love digging through it.

that sounds more like what I would do
I like being able to rearrange things
