Is a fox a cannibal

YES, a fox WILL eat another dead fox. It has been reported by naturalists and proven in scientific studies of feces and stomach contents. I can personally attest to the fact since I have seen a very young fox eating an adult fox carcass. Considering the condition of the young fox, I suspect it was very hungry and the carcass could well have been it's own mother as we live near a busy highway resulting in many fox injuries and fatalities.
