Diet

Foxes are omnivores.[7] The diet of foxes is largely made up of invertebrates. However, it also includes rodents, rabbits and other small mammals, reptiles, (such as snakes), amphibians, grasses, berries, fruit, fish, birds, eggs, dung beetles, insects and all other kinds of small animals. Many species are generalist predators, but some (such as the crab-eating fox) are more specialist. Most species of fox generally consume around 1 kg of food every day. Foxes cache excess food, burying it for later consumption, usually under leaves, snow, or soil.

Domestication

The Russian Silver Fox, or Domesticated Silver Fox, is the result of nearly 50 years of experiments in the Soviet Union and Russia to domesticate the silver morph of the Red Fox. Notably, the new foxes not only became more tame, but more dog-like as well: they lost their distinctive musky "fox smell", became more friendly with humans, put their ears down (like dogs), wagged their tails when happy and began to vocalize and bark like domesticated dogs. The breeding project was set up by the Soviet scientist Dmitri K. Belyaev.

Conversation

Foxes are readily found in cities and cultivated areas and (depending upon species) seem to adapt reasonably well to human presence.
Red foxes have been introduced into Australia which lacks similar carnivores, and the introduced foxes prey on native wildlife, some to the point of extinction.
Other fox species do not reproduce as readily as the red fox, and are endangered in their native environments. Key among these are the crab-eating fox (Cerdocyon thous) and the African bat-eared fox. Other foxes such as fennec foxes, are not endangered.
Foxes have been successfully employed to control pests on fruit farms while leaving the fruit intact.

General characteristics Of foxes

In the wild, foxes can live for up to 10 years, but most foxes only live for 2 to 3 years due to hunting, road accidents and diseases. Foxes are generally smaller than other members of the family Canidae such as wolves, jackals, and domestic dogs. Reynards (male foxes) weigh on average, 5.9 kilograms (13 lb) and vixens (female foxes) weigh less, at around 5.2 kilograms (11.5 lb). Fox-like features typically include a distinctive muzzle (a "fox face") and bushy tail. Other physical characteristics vary according to habitat. For example, the fennec fox (and other species of fox adapted to life in the desert, such as the kit fox) has large ears and short fur, whereas the Arctic fox has tiny ears and thick, insulating fur. Another example is the red fox which has a typical auburn pelt, the tail normally ending with white marking. Litter sizes can vary greatly according to species and environment - the Arctic Fox for example, has an average litter of four to five, with eleven as maximum.[5]
Unlike many canids, foxes are not usually pack animals. Typically, they live in small family groups, and are opportunistic feeders that hunt live prey (especially rodents). Using a pouncing technique practised from an early age, they are usually able to kill their prey quickly. Foxes also gather a wide variety of other foods ranging from grasshoppers to fruit and berries.
Foxes are normally extremely wary of humans and are not usually kept as indoor pets; however, the silver fox was successfully domesticated in Russia after a 45 year selective breeding program. This selective breeding also resulted in physical and behavioral traits appearing that are frequently seen in domestic cats, dogs, and other animals, such as pigmentation changes, floppy ears, and curly tails
