Do sulcata tortoises require a vegetarian diet? What is their shell made of, that it can grow so abnormally due to an improper diet? How sad that they are so little and already someone has taken less than the optimal care of them. I read the article in luckies4me's post - that they need warm temperatures, they don't always move slowly (was Aesop wrong?) and no, they don't swim, which is contrary to what I thought. A very dumb question, are tortoises and turtles different?
