My oversized orange cat was very confused by this as he could not wedge his body into this. For that, I can't blame the scratcher, only his penchant for overeating and snacking and not exercising. My moderately-sized calico, on the other hand, loved it! I didn't even have to use the free catnip to entice her in. She's spent plenty of time napping the afternoons away in it, which makes it entirely worth it.
