Tweety Bird, famous cartoon character, always bewares of the cat attacks, in reality the birds are also necessary to do so, however, they aren’t able to escape such hunting like the lucky Tweety Bird always to be.
Cats are actually the natural birds hunters, even in the high-density urban environment as well. The researchers conducted a survey of several parks and found that about 47% of the death of all birds were caused by the cats.

It is estimated that every year cats in Britain kill about 275 million various animals, in which there’re about 55 million birds.
