"Red Foxes are largely carnivorous. Red foxes are solitary hunters and the majority of their diet consists of invertebrates, such as insects, mollusks, earthworms and crayfish. They do also eat some plant material, especially blackberries, apples, plums and other fruit. Common vertebrate prey includes mice, rabbits, birds, eggs, frog, small reptiles, fish, and even worms. They usually hunt alone. With their acute sense of hearing, they can locate small mammals in thick grass, and they jump high in the air to pounce on the prey."~from Alaska Nature Foxes are generally monogamous and raise their pups together often with the help of "nanny" foxes (not yet breeding females).
