If a cat always leaves a pellet of poop on the floor after defecating, there are three possible reasons:
1. The cat's rear end fur is too long. After the cat defecates, some feces remain on the fur around its rear end and fall to the ground when the cat leaves the litter box. The owner can clean the fur around the cat's rear end to solve this problem.
2. The cat may be having loose stools, which could be due to an internal parasite infection.
3. The cat's diet has been a bit dry lately, which makes it harder to break the cat's stool, resulting in some droppings on the ground. 
The following are good ways to prevent cats from pooping indiscriminately:
My cat is disobedient and won't listen to me. Even though he's learned to use the litter box, he won't poop in it; my beloved new sofa is completely scratched up. As the owner, don't hit or scold him. Give him two oranges, throw the peels at him, and he'll definitely stop causing trouble.
Why are cats afraid of the smell of orange peel? Orange peel has a rather sour and astringent smell. Cats have an extremely sensitive sense of smell, and when they smell a strong, pungent odor, they will instinctively protect themselves and flee the scene. If your cat likes to poop on the floor, you can leave a few pieces of orange peel on the floor after cleaning up.
