PVC Cat Window Perch
Create a hammock-style perch for your cat on a window! Cut four pieces of PVC pipe and use PVC connectors to assemble the pipes into a rectangle with two U-shaped connectors on one side of the rectangle and two T-shaped connectors on the other side. Glue suction cups into the open end of each T-connector. Cut a piece of fabric to fit inside the rectangle with a flap extending from each edge, and sew the flap around each pipe. Attach one end of a wire to a large suction cup and the other end to the open corner of the rectangle, and repeat to create a second suction cup wire attachment for the other open corner. Hang the perch on a window or sliding glass door.
