Foxes dig out dens to provide a safe underground space that is mostly used for raising fox cubs, also called kits. In urban areas, the dens - known as earths - are commonly located under sheds, but they can also be among tree roots, in bushes or on railway embankments. Foxes will visit these burrows throughout the year for shelter, although you may also spot them relaxing out in the open during summer.
Foxes have been documented in Britain's southern urban areas since the s. The expansion of these areas during the interwar period created an ideal new habitat with an abundance of food. The number in urban areas is thought to have increased from 33, in to , in Fox populations are self-regulating, with attempted culls proving unsuccessful. In the s, London boroughs were responsible for their resident foxes.
In Bromley, a fox-control officer killed foxes a year, but made no dent in the population. Urban fox control was abandoned in the s. If you remove a fox from an area, their territory will likely be claimed by another within a matter of days. Removing foxes also usually results in a larger breeding population the next year.
Foxes are resourceful in exploiting new territories. In , as the Shard skyscraper was being built in London, a fox moved in on the seventy-second floor , surviving on food scraps left by workers. Even at the Museum there are a few footprints preserved in the concrete floor of the Darwin Centre collection's space from a fox exploring the site as it was being built.
Red foxes are very vocal compared to other fox species. They use barks, whines and throaty noises for a number of communication purposes, from conversations with their young to alarm calls and aggressive 'gekkering'. Foxes live in social groups of two to six adults, although they mostly forage independently. They use vocalisations to communicate to nearby foxes. A study in Bristol found that when different groups of foxes encounter each other, it almost always results in aggression to defend territory.
Although vocalisation is important for foxes, their keen sight and smell are also key factors in detecting other social groups. Foxes are perhaps best known for their 'screams', which are mostly heard at night, when the animals are most active. The high-pitched wails are made by vixens female foxes , mostly in the breeding season, which begins in January.
It has been suggested that the screams are sounds of pain when foxes are locked together during mating, but this is an urban myth. The screams are actually the females trying to summon a mate. Most foxes are born in March in litters of around four to five cubs. The baby foxes remain with their mother for around two weeks, so during this period she is fed by other members of the social group. The kits emerge from the ground in April and at around seven months old have reached their adult size.
Some vixens will have their first litter at the age of one. Wild red foxes generally live up to nine years. However, on average, foxes only survive between one and three years.
The most common cause of fox deaths is road accidents, particularly for males and younger animals as they start exploring and disperse from a breeding site from August to December. Some cubs will remain with their family group for their whole life, however. Red foxes are one of the most common non-domestic carnivores in cities around the world.
You may have noticed your local foxes looking a little rough around the edges. This could simply be seasonal moulting, or it may be something more troublesome for the fox. Sarcoptic mange, also known as canine scabies, is caused by the parasitic mite Sarcoptes scabei canis. It is highly contagious between foxes and dogs but treatable. The mites can be passed to humans, but they can't complete their life cycle on a non-canine host. The mite burrows into the fox's skin, causing lesions and the iconic red fur to fall out.
This leaves bald patches, whereas when the animal moults for summer, the new coat is already visible beneath. Without treatment, mange lesions can lead to secondary infections that can be fatal in extreme cases.
In some parts of the world, foxes carry rabies. But in the UK and most of Europe, the rabies virus has been eradicated in all animals, domestic and wild, except some species of bat. Foxes can also carry toxoplasmosis, a common parasitic infection.
While foxes can't pass this infection to humans, we can become infected , most commonly through exposure to infected cat faeces. Although toxoplasmosis has little effect on humans, in foxes it can dramatically alter behaviour, such as reduce fear and aggression levels, which foxes rely on for survival in the wild. Foxes are crepuscular, which means that they are most active during the twilight hours, in the evening and at night. If they don't have an outlet for their high energy at that time, they typically destroy anything in sight.
Because foxes are wild animals and they have very specific needs, regular veterinarians typically can't treat foxes. Instead, foxes must see a veterinary specialist when they need medical attention.
Foxes can be spayed and neutered just like dogs and cats. Veterinarians recommend having this done at six months of age. It's very important not to bring your pet fox out in public. If you do and it bites someone, that person can report it. When that happens, the fox is euthanized so it can be tested for rabies.
Medical and veterinary professionals are required to report fox bites to the Centers for Disease Control and Prevention. The cost of a fox varies greatly. It's also important to keep in mind that this price is only for the animal itself. Feeding, housing and cleaning a fox adds up to much more. Foxes in captivity can live up to about 14 years. However, in the wild, foxes usually only live a few years.
Foxes are illegal to own in most states -- and animal rights activists are fighting to make this the law in all 50 states soon. In the states where it's still legal to own a fox, owners need to acquire a permit.
If you talk to wild animal experts, you'll find some that some are OK with the idea of people owning foxes, but most strongly discourage it. Foxes require a lot of time, energy, money and expertise that most people simply don't have. People who have owned foxes in the past say that it's a full-time job. Most animal advocacy groups strongly advise against keeping a fox as a pet.

Like a cat's, the fox's thick tail aids its balance, but it has other uses as well. Foxes also signal each other by making scent posts—urinating on trees or rocks to announce their presence. In winter, foxes meet to mate. The vixen female typically gives birth to a litter of 2 to 12 pups. At birth, red foxes are actually brown or gray. A new red coat usually grows in by the end of the first month, but some red foxes are golden, reddish-brown, silver, or even black. Both parents care for their young through the summer before they are able to strike out on their own in the fall.
Red foxes are hunted for sport, though not extensively, and are sometimes killed as destructive pests or frequent carriers of rabies. All rights reserved. A red fox photographed in Lincoln, Nebraska.
