What makes Hannah so mean?

This is my in-laws cat Hannah.  She was found abandoned by my mother in law a couple of years ago.  Even though she grew up their house, she is still a ferocious, wild cat.  The only two people who can touch her are my in-laws.  One time she rubbed up against my wife, only because the cat thought she was my mother-in-law.  The next visit, my wife tried to pet her only to be hissed at and scratched.  When I stare at her, she gives me this evil look like she plans to kill me in my sleep.
