The one got the name of Schmutzie because it would make a mess of the cage like turn over the water tray and other stuff. The other was Putzie, the cleaner of the two. It was my mother that came up with the names. They lived just over ten years but when the one passed on the other followed soon after.
When I let them out to get exercise, the two favourite spots for them was the top of the oil painting above the fireplace or at the top of the living room drapes. They never seemed to go anywhere else and were perfectly content being there until it was time to return to their cages. When I moved into my first apartment, they had to stay behind because the new place didn't allow pets. Well, they kept my parents company, particularly my mother later! - V
