【Cat-friendly Design】 - Through the study of cats' habits, the bottom-in and top-out design not only fully releases the nature of cats, but also effectively reduces the carry-out of litter, and the recoil when jumping out will shake off a large amount of litter, Therefore, the front door only goes in and out to prevent cats from bringing out litter, while the top door can go in and out at will, allowing cats to jump freely and release energy for added fun.
