Red foxes usually mate in the winter. The vixen (female fox) normally gives birth to a litter of 2 to 12 pups. When red foxes are born, they are brown or gray. Although a new red coat usually grows in one month, some red foxes have other colored coats such as golden, reddish-brown, silver, or even black. The mother of the pups feed them at first by regurgitating food into their mouths.
