I have box turtles, right now I have 6.
At one time I had 30 but most where eaten by a wild cat. Of that 30 most where babies only a few months old.
This is the three-toed box turtle ( Bruno ) that I've had for more than 30 years. é
The turtle pen is about 4 feet wide x 16 feet long.
That mup spot (I have to clean and fill with water) is a small pond that holds water for them.
