Hi, I frequently take my little red foot tortoise to the grass fields for a walk & take in some sun. But on a couple of occasions while she was wandering around I discovered she was chewing on a piece of dried poo or something from a small animal it appears because it was a very small amount, as soon as I noticed it I immediately stopped her & usually this park doesn't allow dogs or other large animals. I heard at the pet shop tortoises will eat their own poo, so I made sure to remove them instantly. I red foot is fed regularly with sufficient amounts of food daily, so it's probably that's just what torts do.
