Pupelf cat scratchers are designed with a pine wood frame and have replaceable and recyclable cardboard inserts which you can re-order in the future. The legs can be attached in 3 configurations to create either a flat or sloped scratcher position to match your kitty’s preferences. We wanted to create a beautiful piece of cat furniture that both kitties and their humans can be proud of and enjoy in the house. And most of all… to save your couches!
