Think 16-18 pounds huge, and that picture doesn't make him look like a kind and gentle cat. Which is fair, because he isn't, really. He's definitely a cat who walks by himself, and all places are alike to him, though he really would prefer that all the warm and squishy places in the house be reserved for him.
He has, however, been fairly careful around M. It's pretty clear that he doesn't know what to think of her, and so is treating her with caution. This is a step up from the usual way he treats things in which Leo and I are interested. His modus operandi tends to be to sit on them, so we can be grateful that he has not adopted this method in the case of the baby.
I caught a picture of him this morning, thinking about what his next move was.
As it happens, his next move was to go and eat some breakfast. I think we're going to be okay.
