This cat-friendly apartment interior design project was created for a client who wanted a cozy, bright and playful home to share with her cat. The goal was to design a space that works equally well for both human and pet. A key element of the project is the integrated metal structure designed as a cat playground, creating pathways that connect different areas of the apartment. These elements also function as decorative features, while the overall design uses light blue and yellow accents on a neutral background to create a cheerful and balanced interior.
