Hi , I have a 1 yr old kitty, named "Bob Marley" he is a Tonkanese. My daughter has a 4 yr old Flame Point Siamese ,named Princess Candy Ann. When Bob Marley came into the house Princess Candy Ann fell in love with him. They play and she cleans him. They never fight or act ugly to each other, except when play time gets a bit rough. My question, Princess Candy Ann is moving with her Human Mother. I would like to get another Tonkanses,for Bob Marley to have a play mate. Should I get a Male or a Female? Or does it matter?
