Kathleen, or Kat as her friends call her, is a typical female Spotted Hyena – aggressive, assertive, dominant, and much larger and stronger than a male Spotted Hyena. She also works as a security guard come mercenary.
In spite of this, she is in a loving, caring, long term relationship with Jessie Vallance. Admittedly it is a femdom/BDSM relationship, and she is his Mistress, but loving and caring all the same!
Kat is also not afraid to resort to "consensual domestic discipline" when she feels that Jessie needs to be lovingly reprimanded for misbehavior.
