At night, I am in stealth mode. Mommy takes my collar off so you can't hear me and my bell coming! (for those of you I haven't yet met, I wear a bell, I love it and Mommy says it helps to keep track of me). She says I have to be in stealth mode after the baby goes to bed to make sure I don't wake the baby up as I do my nightly rounds through the apartment. I love it, now if someone will clip my nails, I could be totally silent, and sneak up on Daddy!
