For Christmas (2009) Jared got my cats these treat balls. You put a few cat treats inside and they are supposed to play with it. As they play with the ball, one treat will fall out when it rolls at a certain angle.
Sugar doesn't care much about playing with them. She just wants me to hand her treats. She's lazy.
Hunny on the other hand will play and play and play until every.single. treat. is gone. There are two of the toys and I usually put about 10-15 treats in each ball. No matter how long it takes her, she will succeed in getting all of the treats. She's pretty funny when she is playing. She looks like a little soccer player. I love my kitten.
