American badger? Ive seen pics of red coloured ones.
Could it be a reddish earth-stained eurasian badger? Dunno if thats possible, from my experience of highland soil it tends to be dark.
Doubt its a polecat, have seen a few run over i dividuals this week,they are a very slender, graceful animal, and quite a dark coat Also got a good length tail.
Not so outlandish to suggest a suposedly foreign animal. My mother woke up to find an escaped capybara in her garden once.
