Well I feed live. Ive had a few little bites on some of my bigger girls. Nothing to bad so far. If done right live is safe. My balls all ive ever fed was live. The corns would take anything. I only leave my mice/rats in the tub for 5 or 10 min. I also dont leave the room either. I only have about 20 balls. Someone with a bigger collection it would be harder for them to watch every snake. Live has worked great for me I dont see myself switching over to F/T anytime soon.
