now my kitty is playing fetch with me! He absolutely loves the plastic tabs from milk cartons. I have to throw them across the kitchen for him and he'll run and get it, then bring it back over to me to throw again.
Usually he'll play for hours tossing it down the basement stairs, running down and getting it, running back up to the top and tosses it down again!
I don't have to buy toys for the cats, they just love playing with the recycling!
