They can be any color that you want them to be. Cats can play, with a mouse, cats can even play with a grouse. Cats can play with a ball, but hopefully will not fall. Cats sleep, but cats do not weep. Cats are sly, but will not cry.
Cats are sweet, and cats meet out on the fence.
Cats crawl up in people's laps, but they can not clap their hands.
