"You're cat is insane!"
Guido described waking up flat on his back -- Killer was sitting on his head with both front paws over one eye, her head bent over and staring intently into his open eye.
That freaked him out.
As she approached old age she lost her teeth. Not all of them. She retained one fang, which she would occasionally clamp down upon my arm. But mostly she slept on my lap or on my chest -- especially in winter. A total heat-burglar, that cat.
As for the neighbors... y'know, I remember my brother being pretty handy with electronics. May I recommend something in the way of Electro-Magnetic Pulse? Or perhaps a micro-wave storm?
I'd recommend a needle-launcher, but it appears you already have one.
