Don't speak baby, but I'd say that guttural laugh/cry is his way of telling the cat they need some time apart. This cat is SO into this baby. If they were in a relationship and that cat came to me for advice, I'd be like, "Honey, you need to get a life outside of the two of you. He has his yellow ball and his short length of tube. What do you have? Just nuzzling him? Go do you."

Still, really loved this. People don't get that cats are very loyal. They just choose one person and everyone else can sit on a sharp stick. Obviously, this cat knows what it wants. It wants to follow its baby boy around until he leaves for college.
