Cat trees, can be so expensive & take up so much room...So after researching, I chose this Kitty City Tower, b/c it is smaller (yet still big enough for climbing/jumping/scratching), it can be easily moved, and easily taken apart/put back together whenever you wish! This is fairly easy to put together, and my cats were already on it before I even had it fully constructed.... They love the 'swat balls' & the scratching post! They like the challenge on figuring out how to get from the first level to the second level (they are still kittens), they also enjoy napping on the top of the two levels, and enjoy hiding in the cubby cube and ''attacking'' each other! I also found that you can place 'stick-toys' inside the top of the 4 holes, this allows for more interaction/more play... I intend on adding a few more pieces to my kitty city, it's a nice option if you don't want to fork out $100+ for a cat tree upfront. It has only fallen once, but other then that tends to be pretty sturdy! Overall, a good value! Would highly recommend!
