Bo has been acting annoyed and whiney all day. He only took a few very short naps (read: not enough day-time sleep), and then yelped out each time I put him down (that would be 4 times) for the night. Usually he has 3.5-4 solid hours of napping during the day, and goes down like a box of rocks by bedtime (under 10 minutes of soothing between 6:15pm and 7pm).
I realized that the source of all this angst is the extra darkness from the total lunar eclipse. He thinks wolves will sneak into the house and spirit him away, and that they will get away with it under cover of the extra darkness. Thankfully, these lunar events only happen every 3 years.
PS the wolves did not make it into the house
