We are going to get a cat tree for Tillie since I can already tell in less than a week with her she wants to climb. I have been looking at armakat, which are in the right price range, although I am open to my husband building a custom job (maybe all wood) for a more clean modern look. I've also considered just doing a few floating shelves on the wall but wonder if that's too boring. can anyone share their experience with what they have or how they built their own? looking to spend around $100. thanks!
