So I bought Olivia an I.Q. (treat) Ball at Petco last week and she had no idea what to do with it and I was the one rolling the ball whike my little hoover ran behind sucking up the kibble. Today, however, filling it with her dinner I refused to roll it for her. She sat there and stared at the balling quivering. Finally she gave it a push and to her surprise kibble popped out! And that was that, Olivia rolled that thing all around and got all the food out!
