"I have two other brands in my home besides this one. The other two are holding up well, and i can replace the cardboard on the inclined one, (which petco also sells). Big mama's board falls apart far too easily, and tiny pieces end up all over the carpet, or in my case, my kittens belly! Don't waste your money, anyone of the other brands will be better. I have three cats, i know. My kitty lounger is the most durable. My inclined scratcher is the best because i can replace the boards."
