Caught something on my trail cam last night that doesn't match any animal in this region

Right so I've been doing trail cam stuff up in the Highlands for years and you do get the odd weird one that turns out to be a pine marten at a funny angle or a red deer half out of frame, classic "what is that" moment that has a boring answer. But occasionally you get something that genuinely doesn't fit anything and those are the ones worth posting. Drop the footage mate, because without it this thread is just us all guessing in the dark. Also worth noting the time stamp, temperature reading if your cam has one, and whereabouts roughly - doesn't need to be exact coordinates, just general terrain. Someone here will probably ID it or at minimum tell you what it isn't, which is half the battle.
