Re: Feeding in your enclosure
I think the only reason to feed in a separate tub is if you don't use newspaper or paper towels as their substrate in their enclosure. When we used to feed our snake in it's enclosure it would end up getting pieces of it's cypress mulch stuck to the mouse and eat it. My bro's snake used to be on a different substrate that was more like dirt and it would ALWAYS eat dirt when trying to eat the mouse. We are now going to keep them in tubs and feed them in there. I think that's fine if there is nothing they can injest other than the mouse.
Re: Feeding in your enclosure
I have always feed my ball in his enclosure live food. Never had a problem ever. As most of the friends here, I think is stressful for the snake to be removed to be feeding.
