There's a couple million posts on this forum - quite a few of them are on this exact topic.
If you search the previous discussions, you'll learn that there aren't many reasons to feed outside of their home enclosure. Next to none of those reasons are founded on anything more than personal preference. Feeding outside of its home enclosure more often ends up having a negative effect on the feeding experience (for the snake, the keeper, or both).
Having said that, where you feed your snake is completely up to you and there are those who have success on both ends. If you choose to have a separate feeding location just know that you're doing so because you want to and not because there's more than that to it.
Oh yeah - for what it's worth, I've never feed a snake outside of its home enclosure. I couldn't imagine doing so now that my collection has matured.![]()
