Badgers are members of the Mustelidae family, along with stoats, weasels, polecats, martens and otters. Globally there are 11 species of badger grouped into three sub-families. Britain is home to only a single species: the European badger (Meles meles).
This behaviour has been observed in both species. In foxes it's probably caching food. In badgers the reason is unknown, although cleanliness of the sett seems likely.
Generally speaking, feeding appropriate food in appropriate quantities is fine. There can, however, be some unforeseen consequences to supplementary feeding.
Hibernation is more than a winter sleep. It's a complete physiological readjustment.
The high-contrast pattern serves as a warning to potential predators that the owner is not to be messed with.
Siblings are genetically related and helping to ensure a brother or sister survives the first perilous months increases the chances some of your genes will make it into future generations.
