19. The Space-Saving Under-Stair Cat Cave
If you have unused space beneath your staircase, transform it into a custom, built-in cat cave. This project involves cutting an opening into the drywall or wooden paneling under your stairs and building a custom wooden cabinet that slides into the void.
The exterior facade can be designed to match your existing baseboards and trim, making it look like a seamless, built-in feature of your home. Inside, the wooden cabinet can be divided into a multi-level play area, a quiet sleeping nook, or a hidden litter box station. This clever use of dead space keeps your cat’s belongings completely out of sight while giving them a private retreat of their own.
