After you have brought a cat tree for your cat, where do you want to put it?
We recommend that you can check the place your cat always in and put the cat tree in the same location. It may make you cat get used to it as soon as possible.
If you brought a high cat tree, you can place it beside the wall, which may make the cat tree more stable.
Locate in the balcony is also a good choice, your cat may like to stand on the top of the cat tree and see the scene over the window.
