Many people are concerned about foxes affected by mange. A scruffy looking fox is not necessarily an ill fox. When moulting in spring, foxes look quite rough, but this does not mean they are mangy. They are typically found in woodland and open country, but their presence in urban areas is increasing. Red foxes are opportunist feeders and eat insects, earthworms, fruit, berries, wild birds, small mammals and scraps left by humans.
