Now, solve this: Pester came running into the room. He came to a fast stop when he saw the dog. He'd seen a dog before, every cat has, and he used to live with a black dog named Henry, but he'd never seen a brown one before. It seemed strange to him, but not as strange as it was to see Linda the brown chicken in the living room last spring. That still confused him. He thought he liked this dog, not because of the color, but because it was small. And it was so hairy. It was a like a mop that could run around. He jumped on his favorite chair and looked down as Maggie ran under it. She was kind of cute for a dog, Pester thought to himself. He layed down on the chair and pawed at her as she ran in a circle under it. He tapped her ears as she went by, and waved his tail like a flag trying to get her attention. After a little more of this, Pester curled up in a ball on the chair and took a nap. <sep>Why did Pester think of a mop when he saw the dog?<sep>It was so black
Solution:
No
