We called him GM because generally his motor was running. He was a big cat, pun’kin and white (the image above isn’t him, but it’s not super far off), and an outdoor cat because my brother, his nominal master, didn’t clean the litter box as often as our mother’s nose preferred. She gave up asking, discarded the litter box, and decreed that the cat, now an adolescent kitten, be ousted at night and whenever the house was unattended.

Some cats wouldn’t have taken kindly to such treatment. GM thrived on it. Although he ultimately died young, he lived with flair and packed more adventure into a half dozen years than other cats manage in two decades. He became a hunter so self-sufficient that grocery-store cat food nearly followed the litter box into the trash. We kept a dish of dry food in the kitchen, but he seldom touched it.

Much to my relief, he showed little interest in killing birds. Nor was he much of a mouser, preferring bigger game. One morning when he was only six months old, he was waiting beside a partially-eaten squirrel, which he’d placed on the welcome mat beside the newspaper.

Whatever reward he was expecting, he didn’t get, and that was the last time he did that. But we could tell he’d had a successful evening if his belly was distended and he was unusually lazy in the morning.

His favorite prey seemed to be rabbits, which he ate in their entirety except for the big bones of the thigh and the fur-ball of the cottontail. My brother and I would tally the kills when we mowed the lawn: clunk from something hidden in the grass, an explosion of fur, and we’d chalk another up to GM. In the summer, he averaged about four a week.

My mother was delighted. The daughter of a farmer, she had no sympathy for rabbits. And in the years we had GM, she had the best gardens of her life. Long before, she’d given up hope that our dog, a 20-pound poodle named Suzy, would rid the garden of rabbits. Suzy was eager to make the attempt, but her methods, although spectacular, did more damage to the garden than to the rabbits.
