Wild Rats. In the wild, the life expectancy for a rat is much lower: 95 percent of wild rats die before they reach their first birthday. A 1-year-old rat would be around 30 years old in human terms. The most common cause of death in wild rats comes from predators, such as owls, hawks and foxes.
Hedgehogs typically live two to three years in the wild. The most common cause of death in the wild is due to predation rather than age. Various resources report a relatively wide range in the maximum life expectancy of hedgehogs kept as pets.
