'Shell Shocked

I'm trying to figure out if Theo is perpetually shocked of if that's the unintentional look his face naturally expresses.

He chases after Thompson and Diego and then looks shocked that they run away or in Thompson's case, hisses at him.

He licks me awake and then looks shocked that I disapprove.

He looks at his empty dinner dish and looks shocked that I don't know enough to keep it full at all times.

He hops up on the sink and looks shocked that the water doesn't just magically appear, that I have to come in and turn the faucet on.

If he truly is living in a state of shock he sure seems happy about it as his natural state seems to be in purring mode.
