The dog Oscar had a costume including a tuxedo and hat. His owner says that depending on whether he wears that hat or not, sometimes it makes him look like a gentleman, and sometimes it makes him look like a gentleman hobo.
Then there was the hatting of the cats.
First, Pete, was convinced to wear the hat. Despite his skepticism, he did not view the hat as a threat. He is here pictured next to an iPad on which is playing the game To Be or Not to Be, the choose-your-own-adventure version of Hamlet designed by Ryan North.
Next, there was Clone, whose love of humans overwhelms all. If a human is within 20 yards, he purrs like a truck. A hat is a small price to pay.
Then, Alexi, who accepted the hat along with some ear scratches. He did not seem to have noticed at all that there was a hat.
He did, however, drool.
