So, the other night Sierra was sitting at the top of the steps, and as I walked passed her I saw a tennis ball at the base of the stairs. I picked it up and tossed it to her. She tried to catch it in her mouth, but missed, and the ball bounced right back to me. I caught it in the air, and tossed it back to Sierra. This time she batted the ball back to me with her nose, almost like a seal. We did this four or five times, both of us seeming to enjoy it, then King walked out of the spare bedroom. This time when I threw the ball to Sierra she caught it, and just laid at the top of the stairs with the ball. They are *so* jealous about their balls. :)
