It works, although I think my cats wish it was a little bit larger in diameter. They are on the large side - not fat, just long-legged and long-bodied - and they look a bit cramped when they’re using it.

I had an automatic cat box ages ago, and my cat learned how to trip it without going, and continually trip it and watch it for hours. I think something similar was the inspiration for The View.

My wife’s cat is a 22 pound Main Coon. He is large and a little fat also.
