I've been owned by as many as 10 cats at once, and I never found anything they ALL liked.
I've got a smaller cat tower right now, and only one of the two cats is ever seen on it. HE would love it, but I think the most the other cat would do is sit on the box at the base, or maybe, crawl inside it.

But the smaller car would LOVE IT. 'The higher the better', is his motto.
