ummm. yes. she is.
Signs to watch for if you think maybe your cat is plotting to kill you :0)
(according to my research on the internet anyway)
~your cutlery often goes missing
~you wake up and find your cat sitting on your chest licking his lips
~ he/she owns the full DVD collection of Dexter
~ your toothbrush has been made into a shank
~ you often see your cat hiding in dark places watching you with an evil eye
~kitty often brings you dead animals? consider this a warning. not a gift.
~kitty sprints out of the room at lightning speed when you enter? hmmm. that was actually a failed attempt at an ambush.
