I know a lot of people have their own ways of fattening up leos, and some people won't agree with me. I don't believe in them getting "addicted" to wax worms, they just get VERY picky when they get too many. Think of it this way, If you let a kid eat cookies for dinner everyday and then try to get him to eat brocoli instead, he's going to refuse. He's not addicted to cookies, He's just spoiled.
I don't use wax worms to fatten them up because they don't have any nutrition. After talking to a lot of breeders of different types of herps, I've learned that really nutrisious foods fattens them up in a healtier way. This means gutloaded mealworms (silk worms are better though).
When one of my girls got sick she lost half her body weight before the infection was gone. After a strict diet of Ca and Vit. dusted gian mealies she has already gained most of it back.
