I have a large room devoted to my foster cats whic contains a cat tree in it. They LOVE to climb all over it and hide in its nooks and crannies!

Pros: Lots of places for adventure or to hide away

Cons: Somewhat expensive

our bigger cats love to climb all over it sometimes they like to sleep on the top

Pros: great

Cons: none

My older cats like it alot,to sharpen their claws and to just hang out.

Pros: Great for old cats

Cons: Alittle big

problem is that in a small house like mine it's tough to find a place for a large tree. smaller trees spread through the house work better for us.

Pros: lots of play area

Cons: none

Cats will climb on anything. If it is high up they will get there. This is nice and fun for cats.

Pros: looks cool!

Cons: none
