i let my russian tortoise walk around my backyard and left him unsupervised for 10 minutes and now i can’t find him. the backyard is surrounded by bushes and mulch and completely secure so there’s no way he could get out.he’s been gone overnight.
is there a common place where they like to hide? any tips on how to find him?

First get on your hands and knees an crawl around and look for holes you say it is secured but until you do a tortoise eye level check, you can’t be 100 percent sure. If it is still in your yard it will come out early in the morning and sun itself, put a favorite snack out for it in one or two spots and keep an eye on it. My russian escaped a few year back and my neighbor found it, she was screaming her head off, saying it is gonna bite me, I had to explain to her that her toes were perfectly safe.
