I started doing this a couple years ago… A couple times a year i do a major trim on trees and bamboo, a mulberry tree specifically. so i pile up the branches in his enclosure and he just bulldozes through them. I also hide little snacks in the pile of branches for him to find, like a couple pieces of fruit or veg i have on hand. and depending what i cut he gets built in snacks like mulberry leaves. after about a week when he’s tired of them and the leaves fall off i take away the sticks and gather up the pile of leaves for composting. It’s a nice free way to change things up and turn trash into tortoise treasure!
