Stop being mean to cats!!
You will suffer in their day of glorious dominion over humans which will one day be upon us.
I'm now getting visions of an awesome
action movie in which a solar plasma storm, or something, turns all household cats into beasts the size of cars. Who then decide to eat us, because kibble don't cut it no more.
The rest is pretty much your standard zombie movie, except with lots and lots of human/mega-feline violence.
