Just like the title says, a lion with polyorchidism would have four balls. This would not affect much except that as a king, he’d have double the amount of stud slots.

Ideally, this mutation is obviously not lethal and because of the advantages it brings being similar to Double Uterus, it would be non-passable except with the help of an item like lion meat.

Physically, there’d be no changes in the lion’s art. Unless like…y’all want big balls lol
