Profile for meancat

 I have had many cats growing up ~ but living in the suburbs, everyone had outdoor cats and it was quite normal to hear the cat fights at night in the distance but we never really took too much notice.  Our family cat would come home missing a chunk out of his ear, fur missing etc.  Now, many years later and older, I have an indoor cat.  She's lovely.  Very quiet, clean and self sufficient.  I adopted her from the animal shelter.  She was approximately 5 years old at the time.  Never socialized with other animals or people.  It has taken almost 2 1/2 years for her to be affectionate with us, her owners (just two of us) but hates everyone else.  She is an aggressive cat, that is for sure.  Now my daughter has moved back home and brought her  3 year old fixed female cat into the picture.  Its been one month of horror so far.  My cat, being a female, fixed, and on two occasions has gone crazy chasing her and wanting to, I'm quite sure, crucify this poor cat.  That is my story, haha.  HELP
