We do not breed them. I want too lol! But they are still young right now. The smallest one tiny is my sons, and he is a lot smaller than the other 2. Pebbles is small, fattie well he is bigger than the other 2. Pebbles and fattie are in the same enclosure. We bought them from a store. Pebbles and fattie have always been together. We won’t separate them right now. They get along so well and are always laying on each other.
