If you are only in there to feed them, then there is a small problem... There is absolutely no way that the snake will associate you coming into the enclosure as dinner time.

If you are in there pretty much every day cleaning, changing water, examining the snake, checking temperatures, then there won't be any association. I think the only association he may make is when you bring a rat into the room, he will know it's time to eat.

I have fed my ball, Amani, in her enclosure since I got her last November. She has never hissed, struck, or tried to bite me while I am getting her out of the tub. I can clean around her, and all she does it look at me. The little Rosy is fed in his tank too, but he's so easy going, I doubt he has a care in the world what I do to him. Little toot.

Anyway, it's just so much easier to feed her in her tub because I didn't have to buy a second tub to put her in while feeding her. People with larger snakes just don't have a choice. Rubbermaid can't make any bigger tubs, LoL. It just wouldn't be safe to get a 10'(or much longer) long snake out of it's enclosure just to feed, and then have to put it back while it is still in feeding mode. Just not too safe, especially if you don't have a second person around to help out in case something does happen.
