How do you find out if your leopard gecko is a girl or a boy?

When mature a male has a v shape of pores at the base of his tail, (underside) females don't.
Check a Vet,

They know Gender's for animal's, If they don't allow a leopard, You have to choose a good Vet, & a Leopard is a wild animal, I hope you find a place to check it's gender!

Good Luck!

Keep it safe & sound
