I just had the one. Rescued him from someone when I went to their house with a friend and saw him dying in the corner. I didn't even know this person but told them I would pay them for him and they let him go for a hundred bucks and I got him all better again!
They're awesome little critters. I left mine with a friend when I moved. I had to dwindle my animals down quite a bit when I moved here. I still get pictures of him and updates on him all the time. I miss him.
