I've had a leo before. I got her as an adult and she was already eating mealworms with crickets twice a week. She would put away 15+ mealworms a day and eat around 4-6 crickets on the days she ate crickets (dusted of course).

Now I have this young leo. She weighs 16g and she just eats crickets. I bought her from Just Lizards. He said I could start switching her to mealworms but how exactly do I do that? I can easily breed my own mealworms and I'm trying to get my colony started. Crickets I can't breed until my husband and I are in our own place and they are so darned expensive.
