We have one similar to this at the shelter. Its great because a bunch of cats can play on it at the same time. Kittens have a lot of fun running up and down and jumping from level to level.

Pros: Can entertain several cats at once

Cons: spendy

Pretty cool to me, its perfect for cats and gives them a way to stay fit and have fun.

Pros: lots of jumping space and fabric to scratch.

Cons: mite be too big, can be a pain to carry.

My kittens play for hours on it. It's fun to watch them play.

Pros: My kittens play for hours

Cons: none

This piece is attractive and blends in well with the decor, and the cats like it.

Pros: the cats like it

Cons: none

I have never understood why these darn things are so expensive, but this one is good quality and lasts quite awhile. Cats love it and it has so many perches which makes it even more enjoyable for the cats.

Pros: Great entertainment, saves on furniture

Cons: Expensive
