I like to use alphalfa pellets (rabbit food). Its cheap and can be injested without problems and is good for spot cleaning. You don't want it to get soaking wet as it can mold but I have never had a problem. I feed pinkie mice to my females when they are breeding otherwise it is a rare treat. Definately not something you want to feed alot. Crickets dusted with calcium/vitamin powder and fresh greens should be theitr main diet with meal worms occasionally. The mealworms and mice are high in fat and obese dragons will have health problems. Breeding females can absorb much higher amounts of fat so they get alot more of these items.
