Do opossums eat chipmunks

No. Possums do not eat rats.

Possums' feeding habits range from omnivores (the Common Brushtail possum) to specialist browsers of eucalyptus (Greater Glider), insectivores (Mountain Pygmy Possum) and nectar-feeders (Honey Possum).

In the wild, they eat young shoots, leaves, flowers, nectar and fruit of a variety of trees and shrubs. They also feed on insects. They do not eat fish or other mammals.

Note: Possums are quite different animals from the 'opossums' of North America.
