Loads of things
Gomez coming into bed for a cuddle does, as he goes through stages of being such a wuss that he won't come out of hiding.
Morticia has a Giddy Kipper that she adores and sleeps on, full length - she looks so cute covering the kipper up and then she'll wake up and beat it up, throw it round the room and stalk off in a huff
She'll glare at one of the boys if they arei n her box, or on her side of the bed, until they get the hint and move. She never has to do anything, just look at them.
Baldrick wakes us up at stupid o'clock most mornings - it makes me grin when he wakes OH up instead of me
And he'll go round the furniture on his side, pushing himself round the furniture with his back claws/paws and then goes mental attacking anything in his way (human arms/legs etc).
Ellis is a wonky little cat who can't move one of his hind legs properly so he simply brings a grin to my face on the very rare occasions he manages to get enough motor control to scratch his own neck with that back leg
My yard cats just make me smile every day when I think what they used to belike, especially one of them who was feral for many years before becoming tame. They all come trotting out to meet the car, every time I turn up, and that will always make me smile.
All of them just crack me up when they're playing generally, though. One of the yard cats will follow me round the field chasing little dried balls of horse muck which is hilarious, and I'm sorry to say I do laugh when she gets chased by magpies, too. She trots along with her head down, pretending she's ignoring them while getting as close to me as she dares for protection
