My cats love this thing...I usually buy the flat cardboard pieces at the store, but I think they enjoy the angle of this one. We've gotten a lot of use out of it by rotating and flipping the cardboard, but it's now about lived it's lifespan. I wish there were replacement cardboard inserts that I could purchase for this, as the base is still in good shape. I only gave it a 4 out of 5, because I thought the base was actually wooden. It's not...it's more of a sturdy, fancier cardboard. Had I known that, I probably wouldn't have purchases it, just because the price is a bit high for what you're actually getting.
