I suspect most kids who would throw water at a cat like that would not be very good liars about it. Also, adults tend not to dump water on kids for no reason. I would definitely take the time to pick apart what happened, before going full papa bear mode.
I might be pissed, but my instinct would be to find out who I should be pissed at first, before going on the war path.
Unfortunately so. I know I’m slightly weirdly wired.
