Y'know... my initial reaction was kind of a mix of "Yuck!" and "Whoa... WTF, that's insane!". But the cat was already dead... he didn't kill it for this purpose, so there's no animal cruelty angle. And other people taxidermy animals all the time (they just don't put motors and propellers on the paws, go figure). Equating it with violation of a corpse is rather over the top.
I think I'm going with "tacky" as my adjective of choice.
If the world isn't making sense to you, you're either drinking too much or not drinking enough.
