When teaching a cat to use cat litter, the pet owner first needs to choose a litter box that is suitable for the cat. You can try to buy a larger and deeper litter box to avoid the problem of the cat excreting outside the litter box in the future. Then throw the cat's feces into the cat litter, pick up the cat and put it in the litter box, then grab the cat's feet and make a scratching motion in the cat litter, and finally let the cat smell its own excrement. . Generally speaking, after teaching this a few times, the cat will automatically defecate in the litter box.
