Any ideas? please help, very curious.

I would like to figure out what my lovely Oreo is. She has a very strong personality and stubborn in her ways, legs on shorter side with slightly longer body. Not very physically affectionate unless on her terms. Reminds me of a Maine Coon mixed work something. She is a cancer survivor. I have tons of pics to share for input.

That pattern, color spots and much white, is called for Harlequin. 

Probably a longhaired domestic, very pretty and handsome.  Also quite peculiar with this nose-piece!  

Good luck!

Thanks
