Has there actually been cases of actual sex between large felines and humans and have the humans presented evidence that they did in fact shag a large feline?
Anyone who has ever been able to have sex with an exotic animal was probably smart enough to realize how easy it would be to find out.
There are some pictures of people handling big cat genitalia, but no sex as far as I remember.
Pretty sure some smart ass vet or excentric millionaire who's got themselves the chance to be around a sexy cat has managed to do it, but yeah, pretty hard to say they'd produce any shareable evidence
Its the same like with bears its most likely possible but very rare...I have been told in big cat management that the ratio of a feline becoming very tame and attached is about 1 out of 20...then you need to have that access and handraise...and they are still rather moody
