8. Hidden Built-In Cat Playground

For those who prefer subtlety, integrate the playground directly into cabinetry. Build cat tunnels inside bookshelves, hidden cubbies in media units, and discreet entry holes along the base.

Paint everything in the same color as the wall for a seamless look.

Guests may not even notice it’s a cat playground — until they see your feline magically appear from a hidden nook.
