LOL! Was it a Siamese? My mom had one that would lurk on the highest places it could (even on top of open doors) awaiting unfortunate humans. I had a ferocious woodchuck in my back yard far more charming (kicked cat butt). We got to an understanding - and it wasn't wired to kill everything that moves.
Nope, just a big grey cat. It does love plastic, and pulled a sheet of bubble wrap on to the stairs. That was exciting when I stepped on it in the dark.
