I have a neighbour across the street who has upwards of six or seven cats. They are always up on the roofs of houses, balance-beam-walking across fences, and sleeping under parked cars. A few weeks ago I caught one streaking past me with something in its mouth, and I realized that a few of the cats were sneaking into my backyard to catch the birds that usually congregate in the trees there. Sneaky buggers. So that inspired this little drawing - a bird's revenge.
