The cat suddenly stops pooping in the cat litter. It may be because it is emotionally unstable, or it may have a smell in the cat litter box that it doesn’t like. The main reason why cats don't poop in the right place is because of the smell, which is that they regard the other place as a toilet instead of the actual litter box.

The way to correct it is to first use a shovel to move its feces elsewhere into the cat litter box, and then clean the smell there. Using soda water is a good way. If you are still worried, you can spray some alcohol on it. Or toilet water, the cat hates these smells, so it will not poop there, and then it will find the location of the litter box, where the smell of its poop is already there.

If this method is not effective, you have to use the "water gun correction method" to correct the abnormal behavior of cats. First buy a small squirt gun, and then whenever you find that the cat is not in the correct position to defecate, spray it first. Cats are afraid of water. Over time, they will know that they will be punished and will not poop there.

It is recommended that the cat litter box be disinfected frequently.
