a diet like that and he won't be 14 inches for long! Seriously. With that amount of food he should grow fast. There is some controversy over the proper way to raise a reptile, some say if you feed them to much and they grow too fast, and that will shorten their life span. I am of the school of thought thats says a growing lizard's food requirements aren't much different then a humans. Basically, when they are babies and juveniles nutrition is important as they are developing and is the worse time to restrict their diet. When they reach adult size however they need a lot less food, my adults eat about three fuzzies a week, and less in the winter time. If there is a problem with waterdragons having short life spans, its not from eating too much as they were developing, but from eating too much as adults, and I think its safe to say that the same applies to us humans as well. Anyway my point is a pinkie a day sound great for a baby but you better watch out as he gets older that he isn't too fat. Eating at that rate he could reach adult size in a year or less.
