I recently got this Armakat cat tower and my kitties love it. It was on sale at thecatandkittenstore.com for much cheaper than a pet store and the shipping was free! We have three cats and they love to climb this thing. It also has scratching posts built in.

They included these little hanging poof balls as well, but they were kind of useless because they were pulled apart by my cats in a matter of minutes.

My cats finally have something to climb besides my computer desk, and they all sleep on it too.

Pros: cheap, cats love it, easy to assemble

Cons: ---

I do not have this style, however, I am on my second Armarkat cat condo. The first one got so much use and love the higher level broke off. I still have it at its without the top level in my computer room, but I bought another high one to have in my living room. I can't say enough how much my cats use it and love it. The many siscal rope scratching posts on it are used constantly by my three cats. In my first one they wore through the rope on two of the posts....imagine how much my furniture was saved. I bought mine through ebay and got what I felt was a pretty good deal.

Pros: The siscal rope scratching posts, many styles, cats love it!

Cons: Could be a little more durable because the cats are rough on it

When I adopted my two kittens, the adoption center recommended this cat tree. My two kittens love the tree. They always trace each other on this tree and they sleep on the top shelves at night. This also keep the cats from climbing our furnitures. One of the best investments I made for the kittens. The only thing is -- the design is a little top heavy.

Pros: Satisfied cats' climbing instinct

Cons: A little top heavy

we have had ours for 2 years and love it. the cats like the ability to get high up and look down on everyone. its a great place to escape from the children or dog, easy to tighten when you need to.
easy to clean, and it has held up to my 2 yr old climbing it occasionally.

Pros: strong, easy to build, cost,

Cons: just need the space

I love this cat tower. The design is great with the palladium window opening to the cubby hole area.

This tower is multi-functional. A climber, claw scratcher and cuddle-up sleep areas. Great for one or more cats!

And looks good in the home, too!

Pros: A tree and cubby

Cons: None
