The real fire fox in nature is actually called Red Panda, Ailurus fulgens, an endangered species. It is is a mostly herbivorous mammal, slightly larger than a domestic cat (55 cm long). This red panda has semi-retractile claws and, like the Giant Panda, has a "false thumb" which is really an extension of the wrist bone. Thick fur on the soles of the feet offers protection from cold and hides scent glands. The Red Panda is native to the Himalayas in India and Nepal and southern China.
