Yeah honestly even though everyone who feeds F/T claims that feeding live is extremely dangerous and can kill your snake, i have had no issues with it.

Thawing out rodents and making sure they are the right temperature is just a pain. Just throw the rat in there and let your snake do what they were INSTINCTIVELY taught to do, hunt and kill prey...

Also a consider pre killed and frozen/thawed to be 2 different things. Chances are if you were feeding your snake pre killed prey which is killed or stunned right before feeding, he would eat them like candy. But feeding F/T is a lot more difficult for a snake that has been eating live it's whole life for over 2 years.
