I was going to do a long, satirical spiel on how you're abusing the poor cat and should be dropped from a ladder yourself, but I'm feeling too lazy right now. (Although you should drop a human at some point.)
Or maybe an equally satirical one about how you should have crowbarred the cat For Science, since after all "It's Just A Cat!"
(Just to be 100% clear for the slower students, I do not actually agree with either of the above arguments and have little patience for those who do. The first makes me roll my eyes and sigh. The second makes me bust out my own crowbar.)
But you should definitely have introduced the crowbar in a harmless "cat toy" way, with a feather or string or just showing it to the cat so he can ignore it.
Also, I'm curious about that thing on the back of his neck. What is that? Leash-attach collar? Electrode?
