I confess to using non-escape proof feeding containers on a regular basis. I sell Avon, so I have a lot of boxes around. I often feed mine in a newspaper lined box. The obvious caveat to this method is that I NEVER TURN MY BACK while feeding them in these.
Some of mine have the habit of backing up and over the side of open containers, so that wouldn't be relaxing for me!Aye, I also use just regular open sweater boxes but I am with them constantly while they are eating. It might sound strange but I find that feeding my snakes is very relaxing after a long day of work. I usually sit down to something interesting on TV and feed them one at a time.
