My parrot, Xiao Wu, once fell seriously ill and nearly died. During that time, I had to bring him to the office to care for him, feeding him a porridge-like mixture every three hours. Standard bird perches were difficult to clean, so I designed this magnetic bird perch myself. It can accommodate two types of magnets—10×3 mm and 5×3 mm (the only sizes I had on hand)—and allows for quick, one-step assembly and disassembly. When it gets dirty, you can simply detach it and rinse it off. A tray underneath collects droppings, keeping the desk clean.
