I was wondering how to tell the difference between a male and a female leopard gecko? Are they to young if they are 4 to 5 inches to tell. I really need to tell the difference between my 2 Leopard Geckos.
Try googling it. There should be lots of pictures comparing the two.
Males have larger bulges beneath their vent as well as a V-shaped row of pores that will secrete a waxy substance. Look carefully. Sometimes they're hard to see, but you'll know them when you see them.
Females don't have either, although sometimes you might see a female with slight bulges but no pores.
