Cats do have the habit of actively burying excrement after urinating and defecation. This habit is not an unnecessary move, but comes from the survival habits of their wild ancestors. There are several specific reasons:

1. Covering the smell

Cats burying feces is a unique behavioral habit formed during the long-term evolution of cats. It is mainly for the needs of survival, preventing natural enemies from finding themselves through the smell of cat feces and urine, and also to prevent themselves from letting their prey smell the smell of cat feces and urine during hunting, which leads to hunting failure.

2. Naturally, cats are a very clean animal. After pulling feces, cats will habitually cover them with sand to avoid polluting the environment. Some cats not only bury feces and urine, but also often lick their butts, which are all manifestations of cleanliness.

3. Eliminate the threat

Before cats are domesticated, they will hide their own traces in order to prevent larger and more ferocious animals from attacking them. Although they have been domesticated now, they are still wild, so burying the feces after shit is also to cover up your health and avoid being easily attacked by the same people if there is any health abnormality.
