Quote from the author:

"The Ball was a gift and currently lives with the Squamiger. They occupy different nitches in the cage but do interact. As I mentioned, the Ball has in the past taken mice right out of the mouth of the Squam. Other than that one incident they get along fine. Many Zoo's are now setting up mixed environments as long as the species get along."
