Items Needed: An old suitcase with a hard outer shell. Strong glue: super glue, crazy glue, wood glue, gorilla glue, or any glue that's really strong. 4 Wooden legs – approx. 4-6" tall and squatty looking works best for stability. Paint (optional to paint the legs before you put them on). Books or heavy objects to weight down the suitcase while the legs dry. You'll also want a pillow that will fit into the suitcase – which you can also make yourself (see fleece pillows). And some decorations that you or your cat will love. Instructions:
