I saw some of these two months ago at our snake show. I went home and looked them up and watched videos. There was one adorable one I remember watching with a mother nursing in a tiny cap/lid. Well, today I went and got some of these guys. I had to. Who would have though my snake addiction would get me into rodents. I have so many rats and ASFs and now pygmy mice! I am excited, they are already fun to watch. Wikipedia says in the wild they stack pebbles outside their home and in the morning lick the dew from them.
