Thanks, that's good to know. It did not come right off with some splashes of water but it does look like the substrate stained him. He burrowed into it a couple days ago and sat in there for a good while.
It's something I truly love to do!!! I love cutting up fruits for the Red Foot Tortoise and love to pick weeds and grind up some fresh cut grass!!! Today I'm mowing and all the shredded up grass Is going to be feed to the little guys and some mazuri for desert.
