I too hear a varied opinion on both ways. I feed my boa in its enclosure, for mine it's what he is most comfortable with. When it's feeding time I would almost for sure get bit if I tried to take him out when he's hungry, as soon as I open the top he knows whats coming and he is eying it and ready to strike So for me it would add more stress to my boa to remove him from his enclosure and feed him elsewhere. If you are feeding live, which is how I feed, it's extremely important to keep and eye on the rat and make sure you never leave a rat unattended in the snakes enclosure. I know that some say that there is a lot of risk to feeding live but if done properly it shouldn't pose any harm to your snake in my opinion. I think it alot depends on the snake and what they are more comfortable with during the feeding process.
