Finally a proper reference sheet!

Quick note about her markings!
Consider her markings, as if on a real cat, somewhat like these images below:

Her markings are not really uniform and do not need to be drawn in the manner I have! This is just my style of fur markings [blend of different shades of orange and black]. People have different interpretations and styles on how to do markings like these.
So please do not be intimidated by the markings!
[side note: She DOES have longer fur near her feet and elbows, I was just bad at drawing it.]

Her father is a large tortoiseshell-colored Main Coon cat from the Russian mountains. He was involved in a rather shady profession. A small mafia-style corporation dealing in stolen or illegally-imported goods or shaking down small businesses to pay for 'protection'.
Her mother is a calico-colored Somali cat from the middle east. [Her mother's direct lineage is mixed from the area.]
Her mother was captured and taken into the illegal slave trade, part of which her father also dealt in from time to time. Upon meeting her mother while transporting the group of slaves to their buyers in a palace, he developed feelings for her. He payed a hefty sum to buy her from the Prince to grant her her freedom. Which, of course, she decided to stay with him.

As a result, Kat is a tortico-colored cat with a slight exotic accent. [When angry and yelling, you can hear more of the Russian half of her.]

Katrina herself makes a living being an entertainer, most of which involves dancing. She's a regular performer at various clubs or exotic, adult-themed clubs as well as a popular performer at festivals.
