Make a puzzle feeder for your cat! Cut slots along the top of each end of a plastic container, cut pieces of wire to fit the length or width of the box and cut plastic pipes into small pieces. Feed the pipe pieces onto the wires, line the bottom of the box with rows of hanging pipes and hang the top row of pipes in the slots along the top edges of the box. Wrap the plastic container with tape to cover the ends of the wires in the slots and toss kibble into the box for your cat to forage.
