New senses, new experiences and a cat litter box designed to explore pet behavior habits can not only solve the toilet needs of cats, but also pursue the cat's sports system. The front door can only enter and cannot be found. It is also the first design concept adopted in the cat litter box. The biggest design point of this product is the flat design of the detachable packaging of the cat litter box, which solves the storage and transportation space in the era of online shopping.
