We had a 9 foot Red Tail that ate live and one Saturday night ( that our feeding night) we drop in a rat with her and watched her strike and constricted the rat. We never left her site and we also watched the rat bite her left eye and we tried to get the rat away from her but she wouldn't let go of it. Never feed live after our Red Tail lost her left eye. Its been 3 year the last time we feed live.
EDIT: This all happen with in 5 mins of dropping the rat in.
