Shelly was working in her Manhattan office one night for the first time. No one else was in the office. At about 9 p.m., she heard a scratching noise. She got a little scared. She looked around. "Hello," she said loudly. "Is anyone there?" Nobody answered. The scratching continued. She got up from her desk. She walked over to where the sound was coming from. She looked in a trashcan. She saw a small rat. It was trying to climb up the side of the plastic trashcan, but it was making no progress. Its claws were useless on the hard plastic. "How did you even get IN here?" she asked the animal.
