On one of the snowiest days this winter, we heard a cat howling outdoors. My son dug through the drifts and tunneled under the porch until at last he saw a starving gray kitty huddled in the far corner. We coaxed him out to eat, but when we tried to scoop him up, he scurried under the porch again. Morning and night, we stuck bowls of food under the porch, until finally he let us pet him. Now, after three weeks, he actually comes indoors and eats and naps on what used to be my writing table. We’ve named him Willy.
