I have finally met the owner of three of the big cats and learned that Tango and Au Au and Loaner are siblings. This neighbor had known for some time that Pinky, also a sibling, had defected to me. And Tango and Au Au are male.
I lost Pinky on February 23, 2011. She survived for a year after three surgeries for an aggressive sarcoma. There is nothing more I can bear to say.
