So turns out the duplex I rent, has squirrels living in the ceiling between my unit and the tenant upstairs. Awesome.
Every few days I could hear scampering sounds on/in our ceiling. That was all I could hear and I just figured it was the cats of the tenant upstairs, playing or wrestling or something.
Straight up, chewing sounds, and ... SQUIRREL CHATTER SOUNDS above my head while I was sitting on the couch. My dog was going crazy, running around the house trying to follow the scampering and chattering sounds.
My landlord is calling pest control today. Sigh.
