Cats are beloved members of many families—and they need space to roam and play! In densely populated urban areas, where gardens, parks, and trees are few and far between, cat-loving architects have designed homes with cozy places for kitties to nap, perch, and move about with ease. Read on for six of our favorite feline-friendly homes.

1. House for Booklovers and Cats by BFDO Architects

BFDO Architects designed this Brooklyn townhouse for a cat-loving professor and a poet. The home features a feline-friendly bookcase with nooks, crannies, and a catwalk on top. Trapdoors on both sides of the apartment allow the owner's cat to access the upper rooms.

2. Inside Out by Takeshi Hosaka

Tokyo architect Takeshi Hosaka created this home for a couple with two cats. Strategically designed openings in the roof and the walls allow the cats to move around with ease.

3. House Taishido by Key Operation

Japanese architect Akira Koyama designed this Tokyo home around the movements of the residents' pet cat. Stepping stone-style shelves and high-level apertures allow the cat to move between the rooms without having to use the landing and stairs.

4. Minimal Living by Scenario Architecture

London-based Scenario Architecture designed this extension to a Hackney terrace home with a wall flanking the kitchen that stops just before it reaches the ceiling. This provides space at the top of the wall for the owners’ two pet cats to walk.

5. Cat Play Enclosure by Indot

Taiwanese interior design firm Indot created a glass and wood structure for cats to perch, scratch and play. The built-in kitty playground appears to be floating, however it's supported by concealed metal pipes.

6. Cat House by Seiji Iwama

Seiji Iwama Architects renovated this minimalist home in Tokyo with step shelves and beams that serve as walkways for the owner’s white cat.
