the last time i was home, i had to improvise...why?because the one above and the one below don't get along too well. The furry one is always jumping on the little one and stealing her food. She wasn't sure at first about eating her food in the tub...until she realized that it wouldn't be stolen by the furry one! She made a few celebratory sounds, that sent to furry one scurrying back to her owner. And she was quite proud.
