The New World rats and mice have many predators, and usually live only a short time. In the wild, these animals usually live for less than a year, but they have reached ages of up to five years old when kept indoors and protected by people. Some species have adapted to humans, and are hemerophile. This has also shown in some common names, such as the Cotton rat, Marsh rice rat, Brown Cane Mouse or Short-tailed Cane Mouse.
