When it was time for a new tree, I started looking at my local stores. The trees were ok but I thought that I could do better price wise online. This tree was bigger and cheaper than what I was finding at my local stores. My cats were climbing on it before we even finished putting it together, they love it. The top unit is a little small for my large male cat but he doesn't seem to mind, he just hangs over the sides (makes for some great pics). It's sturdy, easy to put together and has lots of lounging and scratching areas for my cats. I'm very glad I bought this tree. I only had to wait a few days for it to arrive too. Bonus, my dogs loved to play in the box!
