In the video clip of the Doorway Dangli you can see the creativity and challenge that can be incorporated in order to make cats work for their meals. Sometimes the smartest kitties are the ones waiting for the others who are doing all of the work to dispense some kibble! We call this opportunistic foraging! The orange cat in this video Peaches, had actually become blind in this clip, and while not successful in this video, she is still a master forager despite her handicap!
This toy can be made more difficult by hanging it higher so that the cat must work harder to reach up and bat at the toy.
