Several factors influence their lifespan:
* Predation: Opossums are prey for many animals, including coyotes, bobcats, owls, and snakes.
* Disease: Like other wild animals, they are susceptible to various diseases.
* Habitat: Food availability and shelter influence their survival.
* Vehicle collisions: Opossums are often struck by cars, especially at night.
Keep in mind that opossums in captivity can live significantly longer, up to 6-8 years.
