A self-cleaning cat litter scoop is a type of scoop that is designed to make the process of cleaning a cat's litter box more efficient and less messy. This type of scoop typically features a built-in mechanism that automatically removes debris and waste from the scoop as it is used, making it easy to dispose of the waste without having to manually shake or clean the scoop. Some self-cleaning scoops may also feature a design that helps to reduce the amount of dust and odor that is generated when cleaning the litter box. The materials used to make the scoops are usually plastic, metal or combination of both. They come in different sizes and shapes for different litter types and sizes.
