I think he is about 9 months old and he is our first (the age is only a guess). We have had him for about 3 months and the time frame between feedings have gotten more and more. We feed him live mice, we have tried to switch to f/t with no success. He has very good size to him, I just purchased a scale so I will weigh him this weekend. He has eaten a small rat with no problem before. If he is going to eat he will do in within 5 mins of dropping it in the cage.
