That is exactly what Barking Bracket did.UPDATE 2:
I was wrong about her not doing it again at night while laying down. I started going through the footage again and saw her do it again a couple hours later. I missed it before because it lasts a lot less time while she’s laying down and she doesn’t flap madly. I’m going through the footage to see how many times she did it throughout the night. Her head tilts back in a stargazing position. Maybe some type of vitamin deficiency linked to this?
