Why can't a cat get through with a mouse?

Today is Cat Day in Japan.
because the pronunciation of "2" in Japanese is very much like that of a cat, February 22nd is designated as a cat festival.
today let's answer a question that a child often asks.
Although rats love to steal food, love to bite all kinds of furniture, but also spread plague and other diseases, people hate to the extreme, but from the point of view of the food chain, rats not only never, credit book anyway also have to write it down - they are a free lunch for predators.
Because as long as a slightly larger carnivorous animals, almost no mice, mammals such as dragonflies, foxes, dragonflies, birds such as owls, snakes such as pythons, brocades, amphibians such as bullfrogs, even dogs at home to watch over this matter have a "dog take mice and do a lot of business" name.
why does the cat like to catch mice so much?That's because for cats, mice are the most nutritious meal! Rats are not only rich in protein, but also rich in a substance called taurine, which cats cannot synthesize on their own, but are particularly important for cats.
because of the lack of taurine, the cat's vision will be reduced at night, long-term lack will cause night blindness, can not be active at night! Therefore, in order to have good eyesight at night, cats often catch mice to eat.
the family's pet cat, because can not eat mice, should be appropriate to supplement the taurine content of food, such as sea fish, mammals heart and liver.
, of course, cats have developed a rat-like nature, but also because this kind of food can not eat.
you see so many natural enemies eating mice, mice can live, it is a miracle of nature!In addition to cats, foxes, snakes, owls, bullfrogs and other animals often and mice can not get through! (Ran Hao) Source: Cop China.
