Shame my father in law isnt still with us- he'd've loved that story, as bigfoot was an interest of his throughout his life, living as he did up a mountain in Canada.
The subject of big cats and foxes is interesting. We are inundated with foxes where we live- they raid our bins, fight and fuck in the streets, and run past our house every night, screeching like a hungry baby. Last year, i had an ongoing battle on a Wednesday night to keep one particular fox out of our bins; which ended with me buying dog food and leaving it out for him just before he was due. It worked for a while, but one night i was lying reading in our bay window when i heard our bins go. I opened the curtain to scare him off and was confronted by the biggest fox ive ever seen. At least twice the size of any ive encountered before, he was absolutely massive, grey in the moonlight, and was staring at me with a look that was almost human. That's what struck me most- his eyes. My very loud 'fuck ME!' scared him off, and i got outside just in time to see him scarpering off over the West Hill.
I sat up for several nights, hoping he'd come back, but he didnt.
