Working at my desk this morning with the Chloe perched on the windowsill next to me I was startled to hear her growling. I looked out the window thinking that perhaps there was an animal in the yard that she was growling at but did not see one. When I followed the direction of her gaze I noticed she was staring at the snow plow. Can't be, I thought to myself, cats don't growl at trucks. Later she did it again, when the snow plow returned. I guess we have a fierce guard-kitty on our hands.
