Fox is a common name for many species of carnivorous mammals belonging to the Canidae family. Members of about 37 species are referred to as foxes, of which only 12 species actually belong to the Vulpes genus of 'true foxes'. By far the most common and widespread species of fox is the red fox (Vulpes vulpes), although various species are found on almost every continent.
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 and vixens (female foxes) weigh less, at around 5.2 kilograms. Fox-like features typically include a distinctive muzzl and bushy tail. Other physical characteristics vary according to habitat. For example, the fennec 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.

From all fellow creatures they are the closest and most familiar to us. How is it possible that we anyway forget or even negate, that the wild or with us living mammals have natural requirements and rights, too?
