DIY Tube Cat Condo

Assemble a condo out of cardboard tubes for your cat! Cut a concrete form tube to the desired sizes and cut a carpet runner into the pieces needed to cover the inside and outside of each tube. Glue the carpeting around the outside of tubes, glue the tubes together and use clamps to hold the tubes together while the glue dries. Coat each edge of the tubes with Liquid Nails for a hem and place the remaining carpet squares inside each tube. Drill a hole in the top of a tube and knot a rope through the hole for a built-in cat toy.
