Hi, I have acquired a leopard from my cousin! I took him to the vets today for "his" first check up with me! ( bearing in mind that he is now around 5!
Anyway after the vet had a good look at him, she told me that he was actually a she!! Bing is a girl after 5 years haha bless him!
She also said that females have a flat shell underneath as makes have a concaved shell underneath for mating! So although I'm not a expert whatsoever my guess is female xx
