I was going to get a Russian tortoise to start off with, but I ended up rescuing my current fella, Kurt. They don't need a whole lot of space as a baby, but eventually they need a 30'x30 pen with an underground fence (5') to stop them from digging out. I feel bad when I have to bring him in as he has to stay in a 2x4 pen and he looks miserable. I finally bought him a dog house and got him a nice heat mat. Now he only leaves to graze on his grass when it's sunny.
He loves cactus pads and hibiscus flowers. He still hasn't warmed up to me, but that's fine. He will eat out of my hands occasionally, but he prefers me to scatter his food so he can forage even more. Luckily, because he had MBD he has not gotten into the habit of digging (although he may eventually.) so far, the only digging he's done is straight into hay piles and towel piles!
