The red fox is not a picky eater. They are omnivorous, meaning they eat both animal and plant foods. Usually, more than 60 percent of their diet consists of mammals, such as rabbits, rodents, woodchucks and squirrels. The rest of their diet can consist of fruits, vegetables, nuts, birds, frogs, fish, turtles, eggs, worms, insects and dead animals. In areas around humans, they are known to eat chickens, pet rabbits and guinea pigs, pet food and garbage. Red foxes have excellent senses, including sight, smell and hearing, which makes them great hunters. They spend about five hours during the day searching for food. They will store the food they don't eat for their next meal by covering it with dirt, leaves or snow and marking it with urine.
