The Cat～

The cat is a small carnivorous species of mammal that is valued by humans for its companionship, and for its ability to hunt down rats, snakes, and other such creatures. Cats can be trained to obey simple commands, and have even been known to save their owner's lives. Cats are one of the most popular pets in the US, and possibly all over the world. Recently, a study found that all house cats were descended from a group of African Wildcats, which was a particularly interesting discovery.
