miniature metro system by xing’s world carries first feline passengers in cat town

Xing’s world builds functioning subway system for cats at home

After two years of experimenting with small-scale architecture for his pets, Chinese YouTuber Xing’s World unveils his most ambitious miniature project to date: a fully operating subway system for cats. Built over the course of four months, the tiny infrastructure introduces a complete underground station and moving train, adding a new chapter to his long-running series of playful designs for Cat Town.

The metro joins a growing portfolio of miniature environments that Xing has created, including a pool for cats, a private island, a parking garage, a pet supermarket, a home, and even a small movie theater. What distinguishes the subway is the engineering detail behind it. To realize the design, the designer relied on both his woodworking skills and 3D printed parts, which allowed him to construct the complex station elements with precision. Xing faced the challenges of synchronizing the opening of train and platform doors, as well as constructing a functioning escalator. Instead of letting those hurdles stall the project, he committed to tackling each problem step by step until the full system came together.

The final station includes realistic details that echo urban transit environments, from the train’s arrival sequence to the boarding process. Platform screen doors line the edge, complete with signage and warning strips, while overhead maps and directional boards recreate the look of a real metro concourse. Even escalators, staircases, and waste-sorting bins are carefully crafted to scale. ‘Welcome to Cat Town Station, please give way to alighting passengers before boarding,’ content creator Xing’s World announces in the video tour, where his cats, Mr. Nice and his family, become the first passengers to explore the new underground world. Like his earlier projects, he conceives the subway as a way of reimagining everyday infrastructures on a miniature, pet-friendly scale.

While the subway shows intricate craft and engineering, the process also reveals the ongoing interaction between design and daily life in Xing’s home. Training the cats to use the miniature system became part of the process, mixing playfulness with problem-solving. Xing even jokes that the usual headaches of post-construction cleanup were made easier this time thanks to a robot that was part of the project.
