Prepare a suitable litter box, fill it with cat litter, put cat poop or cat urine on the litter to let the cat get familiar with the smell, and put the cat in the litter box whenever the cat wants to go to the toilet. . Once the cat learns to go to the toilet in the litter box, the owner should provide petting and certain food rewards to allow the cat to form a conditioned reflex.

Once the cat poops in another place, the owner can drag the cat to the place where the cat goes to the toilet, gently whip the cat, and put the cat back into the litter box.
