I always wanted a dog growing up. My parents finally agreed to a cat, so I made do. She knew sit, shake, high five, would "play" the piano, and could be sent off to touch a mark. When my sister's cat came to live with us for a few months, I taught him to sit and to jog on the treadmill. The treadmill trick was no longer allowed after the day mom was running on the treadmill and he jumped on and ran up between her feet.
