I don't have a cube, but I have a ball which works on the same principle. I originally bought to feed a
VERY overweight girl, the idea being she could/would work for her meals. Well
, she would run over once the ball stopped and the food fell out. I got a work out rolling the ball for her and she did move to get to the food. Once her weight was off and when the ball would come out later, she really played with it. She remembered food was supposed to come out of it when it rolled.
