That has to be a baby fisher cat or a really brave / stupid house cat in the vid.
Fisher cats get bigger than your average house cat, and are NASTY. A few years back we had one roaming our neighborhood, and they have a screech that is like a toddler having her finger nails ripped out. I mean, totally blood curdling.
We had friends over and I downloaded a video of a fisher cat’s screech. When I played it, my house cat booked down the stairs into the basement and didn’t come back up until the next morning. Probly thought one of those monsters was loose in our house! Yes, I’m mean to small creatures, but only after they are mean to me first (damn cat wakes me up between three and four AM every morning I’m home).
