This one is good - we have a cat that definitely has "cattitude". She frequently smacks us (mostly my DH, sometimes me) if we pet her wrong. And what "wrong" is can change greatly depending on her mood. She gives our other cat (who is almost twice her size) beatdowns on a regular basis for sniffing her, chasing her, getting pettings (because we are only supposed to love on her), or just being in her general vicinity when she gets pissed about something else. When she smacks, it's 2 or 3 real quick bats with the paw (usually, claws out!)
We've put a lot of this behavior down to her getting old (she'll be 18 this year) and at least somewhat to her health (kidney disease).
Well, lately she has taken to sleeping on the back of our couch. And she sleeps a LOT more soundly than she used to. So, almost every time she sleeps up there, she slips off in her sleep. On good days, she either catches herself before she falls all the way off, or at least falls forward so she lands IN the couch. On not-so-good days, she falls off the back of the couch.
A few days ago, she started slipping off the back of the couch and caught herself. She then proceeded to smack the couch. D@mn couch, throwing her off like that! Smack, smack, smack!

As for our other cat - he's about as cute as can be. When he wants petted, he comes up and taps one of us with his paw very lightly, as if to say "Excuse me please, would you mind petting my head for a moment or two?"
He's also always been a very quiet kitty. Would barely talk at all, and when he did, it was more of a squeak than a meow.
I got the bright idea to try and get him to talk to us a little more by giving him treats when he talked, and only when he talked. I mostly ran these little training sessions right before we went to bed after turning off the TV for the night.
Now, within about an hour or so before the time we usually head for bed, he will appear in the living room and lay out in the middle of the floor, waiting. When we turn off the TV, it makes a click, and that's his cue to get ready. At that point, he perks up his ears and checks the TV to make sure it is off. He then waits. The remote is a rechargeable, and it beeps when it is put in its cradle. As soon as he hears that beep, he jumps up, runs over, and starts a constant stream of meowing and squeaking. And doesn't stop until he either gets treats or I get up and its clear that it isn't a treat night.
