This is Baby - home from the vet on Saturday afternoon.
She just doesn't like the indignity of the whole ordeal. She is not a cat that 'cooperates' with the veterinary staff. (When she goes in for routine office visits, they have to put a tiny kitty muzzle on her just to examine her!)
So she takes it out on Zork when she gets home.
Zork just bides his time and tries to lay low, until she gets over it.
Or maybe he is just dreaming of a road trip...
