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.
According to Wikipedia: Hedgehogs have a relatively long lifespan for their size. Larger species of hedgehogs live 4â7 years in the wild (some have been recorded up to 16 years), and smaller species live 2â4 years (4â7 in captivity), compared to a mouse at 2 years and a large rat at 3â5 years.
