Kittens, generally, can begin to use a litter box at about four weeks of age, and a kitten being raised without its mother or adult cat will take slightly longer to litter train; so, keep this in mind when you begin the task of litter training your kitten. - Place the kitten in the box 1/2 hour after play or meals.
Almost any easily cleaned plastic container can be used as a litter box, but buy the largest box your home can accommodate. A rule of thumb is to get a box that is at least twice as long as your adult cat and as wide as the cat is long.ome litters have perfumes or other additives that claim to help cover litter smell.
