Imagine a life without a single rat or mouse sighting. In fact, consider what it'd be like not to have any rodents in your entire country.
The rat is one of the most common and successful mammals on earth. Even the rat family tree is impressively large. The rat family is primarily composed of members of the Rattus genus.
It's hard for most people to imagine life without rats. We may not see them on a day- to-day basis, but the vast majority of us structure our lives around these rodents to at least some degree.
