Watched it twice too and the second time broke me. The slow pace makes every tiny look feel like a gut punch.

Guessing you still carried way too much food though.

Damn, that must've been a hell of a surprise. I had a squirrel in my AC line once and thought the unit was about to blow up. Anyway, the trick that actually worked for me was putting a one-way vent cover on the outside. It lets air out but the flap only opens outward, so nothing can push its way in from the outside. I also wrapped the vent pipe with that metal mesh wire, the stuff meant for critter proofing, because they'll chew through plastic in a night. If you really want to be extra, check the vent after a good rain too because moisture buildup can attract them back. Honestly, once they get comfortable in a spot, they'll keep trying, so you gotta make it impossible, not just annoying.
