After careful observation, scientists found that the cells that dominate the color and mark of cats appear during the development of cat embryos. These cells first appeared in the form of neural crest cells, initially located on the back of cat embryos, and then these cells slowly spread downward in the embryos.

If the cells spread far enough, the embryo will develop into a pure color kitten, such as all black or all orange. But when these cells can't spread completely, cats will grow white feet, white faces, white breasts and white bellies. So the next time you see a kitten in white socks, you will know that this feature is the result of a combination of genetic mutation, domestication and embryonic development.

Extended data:

Cats with white legs are called "clouds cover the snow" in some places, saying that it will be bad luck for the owner to raise such cats. However, this statement is not reliable. In some areas, there is a completely opposite view about cats of this color. For example, there is a saying that there are four cats with white feet called "four hooves walking through the snow". Such a cat is a lucky cat and will bring good luck.

In fact, the cat's body color is only related to its genes, and it does not affect the owner's luck. The so-called "black clouds cover snow" or "four hooves tread snow" is just a subjective will imposed on it.
