not many people know this, but the tortoise is actually nature's suction cup. Try it! Lick the underside of its shell then throw it up to the ceiling - it'll stick there. Sounds crazy, but it's true!
I think that stubbing a cigarette out on a Tortoise is stupid, all the ash just rolls onto the floor, what you need to do ist to scoop the tortoise out of the shell with a sharp pointy thing, then cut open the shell, Hey preysto you now have two ash trays, far mor sensible.
I threw a stick for my tortoise once. He went after it but.................I'm old now. Has anyone seen him?
Tortoises are great on ice when their legs are tucked in. You don't have to push too hard. You can have a little goal at each end of the ice patch and he can really feel part of the action.
