Mommy - do you have any "yarn balls"?
?Yarn balls? -- "Do you mean a ball of yarn?"
"Yes, a yarn ball" (snicker)
"Why do you want a ball of yarn?"
"Because cats LOVE yarn balls. It's like their job to play with a yarn ball. Can I have one please?"
"Well, you're in luck. I happen to have LOTS and LOTS of balls of yarn."
--- I fetch a small one of scrap yarn....
"MOMMY! MOMMY! I didn't know puppies liked yarn balls. Make Kyra stop stealing the yarn ball away from the kitty."
