Mr. Smoky, one of our cats, has 4 or 5 little foil balls that seem to be his favorite toys. Here is how I think he is playing fetch with me. I put all the balls in the little area in the office where we put all the toys when they aren’t in use. The next morning most of the balls are by his food, in his food dish, in the hall and in our bedroom. Sometime during the day I put them back in their box and we do it again the next day. Funny kitty.
