Skunk Chow

Skunks are omnivores. They can be found eating nuts, berries, roots, leaves, grasses, and even some types of fungi (mushroom-like plants). For animals, they enjoy dining on rodents such as mice and rats, insects, earthworms, frogs, lizards, toads, and birds. Sometimes when they are unable to find live animals to eat they become scavengers eating dead animals left behind. When they live close to people’s homes, skunks sometimes will even get into trash cans eating garbage.

When skunks eat, they do not limit themselves to small meals. They like to “pig out” on whatever food they can find. When there is a large amount of food available skunks get very fat very quickly.
