We have achieved new-pet integration

This morning Barnabas (new kitten) and Powder (staid middle-aged cat) were actually playing together. Awkwardly, to be sure -- Barnabas really isn't 100% confident he doesn't need to be afraid of Powder, and Powder is conscious of her dignity and out of practice in kittenish frisking -- but playing together just the same.

I'm so relieved.
