Does your outdoor kitty need a palace, but you can't afford the ones at the store? Well if you live in a mild climate this might be a solution for you. You just need 1/2" pipe foam insulation, a rubbermade bin, pet bed (optional), and cardboard cutter. The bin was $5, the pipe insulation was $5 and the pet bed was $9. Just cut an opening large enough for you cat, cover the edges with the pipe insulation, and put in the bed. I also bought a matching hand towel for a cover flap.
