This folding cat litter box, taking into account the dual needs of cat toilet habits and family space use, takes "flexibility and space efficiency" as the core starting point in the overall design, and transforms the traditional fixed cat litter box into a foldable storage structure, so that it can switch more freely between use and storage. The overall shape is based on simple geometric blocks, with soft rounded corners and low saturation color matching, which weakens the sense of tools and improves the integration with the home environment, so that the product can appear more naturally in the living space. In the structural design, through the layered folding and rapid unfolding mechanism, the problem of large area and inconvenient storage of traditional cat litter box is solved, and the handling and moving experience are optimized. The internal space is kept spacious and stable, ensuring the comfort and safety of the cat when using it, and through the reasonable entrance height and transparent structure design, the privacy and air circulation are balanced. This design not only improves the convenience of the owner in the process of cleaning and storage, but also improves the use experience of cats, transforming the litter box from a single functional product into a pet household product that takes into account space adaptation, use experience and lifestyle, and further strengthens the overall design value under the scene of pets and people living together.
