Sophie was not your ordinary cat left on the doorstep. She held the high bounce record of her species. In other words, Sophie would be able to make a colossal jump right onto or off any building she wanted, and obtain a steep descent without harm. She was a brawny creature and worth every cent they paid for her company. She was hoarded by building maintenance workers any time they found her wanting a saucer of milk. Even the old sewer drains held up by rotting wood were her specialty in rat hunting, so city workers loved her too.
