A used litter box for cats, clean and well-maintained, in very excellent condition, suitable for kittens up to two or three years old. It saves you effort and time cleaning—the litter box is electronic and cleans itself; you only need to remove the waste bag from the back of the box. It is very convenient. With a regular litter box, you have to clean it three times a day, and even then, by the end of the day, you must change the bag, and odors may still occur. This one keeps the place completely odor-free and very clean.
