Oh, I thought the tortoise picture was your tortoise making his own doggy door through the wall. I agree with the great big liquid and poopy messes too. Big tortoise you need a flat sided bucket. My little Russian tried to dig his way outside through a corner of our home. I figured out...ok free roaming house tortoise doesn't work.He was a house roaming Great Dane. When we had a house roaming tortoise, he just made poop messes.
