If you have a spare room that you need to Catify, check out these incredible cat towers from Korean company CatWheel. They’re actually more like complete jungle gyms, with platforms, ramps, scratchers, hideaways, and exercise wheels. It looks like you can customize them to include anything you want.
I love the look of these sleek systems, including the little hideaways with the stylized cat face cutouts. These would look great in a modern house.
They also have tension pole cat trees that fit between the floor and ceiling. You can attach shelves, perches and ramps to create a customized climbing area.
It’s hard to tell if these can be shipped to the US, the CatWheel website is almost entirely in Korean, but they are definitely inspirational, if you have the skills to create your own. Here’s a great post with info on how to build a DIY cat wheel!
