I read many articles and opinions that Red Tailed Boas will eat whenever food is available until they poop. They don,t have a limit. According to my experience with My Boa, that is not true. I feed my 10 month Male Red tailed Boa live rats since he was 3 months old. He will eat only when he is hungry. If he is not hungry, he will reject the rat. That has happened many times. Even if i wanted to power feed him, i won,t be able to force him to eat if he does not want. I know that different people have different experiences and snakes would react differently from each other but this is what i have experienced so far.
