It's like they pee and poop. In fact, these are the fixed places they marked. If you don't want them to excrete everywhere, you need to prepare a litter box and shovel it once a day, which is easy to teach them. Cats are very clean animals. Generally speaking, they are born to bury poop. You can put it in a few times, scratch it with its paws, or put its poop or urine in it, and it's basically fine. Of course, you need to put others in.
