I miss my cat. I know just what you mean, too. Although I find cats are pretty varied in their personalities. My sister's cats were totally different from mine. Then again, my cat thought she was a dog for most of her life.
Not sure I would want another cat anytime soon, though. I'll be moving soon, and may have to leave my dog behind when I do (with my neighbour, not just . . . behind). Going to be awfully sad if that happens.
