She looks like a dilute calico to me, so I was thinking Calypso.

If you are really looking for a Kate Hepburn related name, hmm. Among her hundreds of roles she played Tracey Lord in Philadelphia Story, one of my favorites... Jo in Little Women waaaaay back when... Rose in the African Queen. [There's a thought, what about Ayque for A.Q.: African Queen -- picks up a tribute to Kate, and a tribute to the ancient cat worship in Egypt several millinium back. Too obscure??]
