My mil gave my cats one of those furry weasle toys attached to a plastic ball that moves along the floor and flips and flops. I turned it on for the cats and went to do some things on the computer for awhile, about a half hour later I got done and was looking for the cats and the weasle, the sliding glass door was open, so I went out....the weasle had gone out the door, down the steps and was rolling on down the vacated road in my mobile home park, and one of the cats was just sitting there watching it go bye bye....it was a funny site.
