Turtle on wheels
After Jim Lee's turtle was hurt in an auto accident, she never regained the use of her hind legs. Instead of letting her die, Lee affixed hind wheels to her shell to help her get around. That's right, a turtle with wheels:
After some weeks Little Bit seemed to have made a full recovery except for the use of her hind legs. So some wheels seemed to be the way to go. Some lightweight model airplane wheels on a wire frame did the trick. The removable wheels were secured by a velcro strip epoxied to her plastron. The velcro strips on the carapace were removed after four months. She was eating, drinking, and exploring all the rooms of my house. Eventually she was able to move around outside as well.
