I personally would never feed live unless I had a snake that was willing to starve itself if it didn't get it.
All three of my snakes readily accept F/T and even though I have no problem with people who responsibly feed live ,i/e watch the entire time to make sure there are no mishaps, It's just not for me.
I have no personal interest in breeding mice, and any refusal of a live mouse would likely turn into a pet.
So happily it's f/t for me. But like I said there are plenty of people on here who feed live safely and responsibly and I support that. I just prefer f/t.
