Love the "poo topics"!!! Lots of poo comes from lots of fiber in their diet. I still don't like to think about any of my pets eating any poo at all!!! I kiss my cats and dogs....Don't know about you, Barb, but every time I go into the tortoise yard, there is new poop! And lots! My dog goes with me as all the tortoise way outweighs him - the largest by 5 times!
Not only that - want to see your tortoises go crazy - let them find some dog poop you didn't know was there! I believe that is an important part of their diet in the wild - animal poop!
