OMFG :yelrotflmao: , you people a F*&!?ing hilarious.
I don't know about your state, but here in California it is a felony to kill a domestic animal (ie dog, cat, horse, cow) for no immediate reason (ie in fear of your life). However I will give you the benefit of the doubt because I have never personally met this particular kitty, kitty. I think the smarter thing to do would be to call animal control, animal save, or SPCA and borrow a trap. Trap the ferocious little creature and take it to animal control, and either the owner will find it and cost them some money or they wont and kitty is gone forever. If it comes back trap it again and keep takin' it to animal control (prices here go up $50 an impound - $50, $100, $150, $200, $250 plus citations), which add up very quickly.
But the cool thing about this way is you wont be in a cell with a guy named bubba callin' you his little kitty, if ya know what I mean. Just do the right thing, I hate to hear stupid $hit happen to smart people............... :beer:
