I went to tell my fortune. The fortune teller told me not to eat mice, snakes and dogs. Why?

First of all, owls should eat voles (mice eat them, but mainly voles), but voles are not the only food source for owls.

Owls are active at night and their eyes are unusually sharp at night. As we all know, voles usually move frequently at night, so according to the survival law of nature, owls will choose to eat mice in order not to starve to death.

Secondly, as far as the biological chain is concerned, mice-level animals, including rabbits, snakes, grasshoppers, earthworms and owls also eat rabbits and snakes, but after all, only mice are active at night and are easy to be caught. Therefore, in order to reap the maximum results with the least effort, the owl's main food is voles.
