Prius V hvac system parts help

Hi there. I left my 2015 Prius V in my yard for 6 mo while traveling. Upon returning rats had gotten in. It’s been a complete nightmare, but I had to disassemble almost everything to clean it: All seats and carpet, center console, dash and all halfway easily accessible parts. This was necessary because the infestation was extremely bad and the smell would knock you over. Before disassembling I checked to make sure the car still ran. Anyway, now that I’m reassembling, I came across a part I don’t recognize. It might be something else from inside my house and not part of my Prius at all, but it looks like part of the cabin fan or hvac system. Can anyone tell me if this is a Prius part?
