I'm not sure what reaction I expect from Watchcat Collette when I say from behind a closed door, "Good morning, Collette. It's 6:11," or "Good morning, Collette. It's 6:55. You won't have much longer to wait," conveying to her that I hear her, but it's not quite time to be fed.
It just feels right to acknowledge her meowing, even though we don't speak the same language.
