Fox

Foxes are medium sized, dog-like carnivores that live in dens, in woodland and shrubland. They are solitary animals, mainly active at twilight and at night. They have ginger or reddish-brown coats with a white underside, white-tipped, bushy tails, black ears and legs, and golden eyes with vertical-slit pupils. Foxes have sharp teeth and a pointed muzzle, and a strong, unpleasant smell. Although they do not appear in the Original Series more than once, they make regular appearances later.

Relation to Clan cats
Foxes are dangerous to cats. They are highly territorial, attacking other animals that step on their territory, so even if they don't eat cats, they will likely attack them on sight.

They are usually dealt with by being driven out by the Clan cats, episodes being described in several books. A strong and healthy cat can chase away a fox by him\herself.

Foxes play a major role in the Clan cats' life. Several cats are named Fox-, like Foxleap or Foxwhisker. They have expressions pertaining to foxes, like fox-length, fox-hearted, or fox dung.

Relation to Twolegs
Foxes are troublesome creatures as they steal poultry from around Twoleg nests. Twolegs usually set up traps to catch and kill foxes.
