Caspian grabs big fistfuls of cat whenever they're close enough. Blessedly, our cats are very tolerant and cuddly. Fin is always trying to lick Caspian's head and hands. Whenever Caspian's on the bed, Fin always lays nearby.
Caspian thinks peek-a-boo is hilarious, now. And for some reason, Caspian is a guaranteed crack-up whenever I sing scales (which I do while curling my eyelashes -- which may help a little).
One of Caspian's favorite pasttimes is "surfing" -- standing up on my legs, holding my thumbs in his fists, and rocking side to side really hard, like he's on a surfboard.
