 What is the nature of love? A sassy, brassy bird lands on a tree limb and moons a cat sitting there peacefully. The cat ignores the bird at first, but it continues its loud and coarse assault. The cat tries force: hitting, stomping, torching, and nuking the bird. Each time, the bird returns, thrusting its bare bottom in the cat s face. Another attempt at ignoring the bird reduces it first to tears then to illness. The cat saves it. Has the cat had a change of heart, or does it just enjoy inflicting pain? Is the bird expressing love?
