Appalled

I think it might have been squirrels (well, the first one) on the peanut feeder.
At least one appears to have devised a working technique for slurping peanuts out of the holes; I shall have to make sure to get larger peanuts next time.

She was, on the other hand, very good about staying well away from the whisker-crisping substances involved in oven cleaning today, so perhaps it takes more than squirrels to produce a look like that, and my lamentably limited primate senses did not permit me to perceive what the whole thing was about.
