I shopped around and found the best one I could in my price range. Most other websites were higher priced. This is something my cat, Potato loves. He doesn't use the bottom compartment but goes right up to the top and sleeps up there for hours, sometimes all night. He loves looking out the window during the day on the top too. His favorite place to sleep has just been changed to the top perch. Only slight negative is that it shakes a little when he jumps on or off it. My son suggested weighing it down. Otherwise, great, strong product!
