First "How To Find Kitty" - Go to the nightclub on the middle level of the city (not the slums) and be a bouncer there. Do that a couple times, and be STRONK! at it. you get a chance, at random I'm pretty sure, to save a cute girl who immediately hits on you. that's Kitty.
Given various aspects of the character, 2 of your no options could be blocking you from meeting her, though.
Honestly, given what she does and how she's written, you aren't missing too much not meeting her at this point - no dig to those that like her, but she does not have a lot of content as of yet, and it makes her a much more limited character than some of the others. I'm sure she'll be better in the future - Indivi is really good at this XD - but that's for later.
