Would a fox attack a human?
A wild fox is described here, along with appropriate behaviour upon encountering one.
According to Wildlife Informer, oxen are mostly nocturnal, making daytime sightings difficult.
This does not imply, however, that oxen cannot be spotted.
Wildlife Online states that no estimates of the worldwide fox population are available, whereas Peturity identifies 37 different fox species.
But just 12 of them are "genuine foxes," as the saying goes.
Because of how uncommon they are, people know very little about how they behave or whether they are aggressive in domestic settings or the wild.
