They got it from Piper the Cat, who proceeded to frantically "attack" them through the glass. They pecked back at her, and for a few moments there was a cacophany of spitting, honking, pecking and clawing. But there were no clear winners. Maybe tomorrow.
You know, if you have pets, you really don't need television.
UPDATE for The Cleaning Lady:
Just moments before, they had been sleeping peacefully and then I guess Frodo breathed in a way Jingles didn't like or something and she set to bitch-slapping him around. Note the dog's paw on the cat's chest in a vain attempt to hold her off before she administered the Ultimate Feline Smackdown. Can a dog also be a pussy? I guess so.
I really love that cat.
