My Leopard Tortoise just died. I had it for about a year, it never caught on to the whole eating/thriving thing. Spent $1300 on vet bills for it, no dice. On the other hand, my Sulcata tort is growing by leaps and bounds. It weighed 3.75 oz when I bought it, now it weighs 18 pounds! She is 13 inches and a grass, dandelion eating pooping machine! She is inside for the winter now, but still eats huge quantities of hay.
Leopard Torts are an awesome species, they don't get huge, about 18", but be prepared for a pet that will probably outlive you! I wish I was closer, I would take this fella off your hands in a second! Whoever gets him won't be sorry.
