To me makes no difference i feed primarily f/t (i can house mass quantities) but randomly i give them live here is why!!!
I just spent close to an hour reading these arguments

I enjoyed them very much. Here is my opinion. Other than the small chances your Live pray item might injure your snake(which is about a 1%risk IF the caretaker is stupid and leaves the live pray item unattended). As far as the "HUMANE" part of it, thats my favorite debate lol. F/t Mice you get in a nice bag, comes in the mail, you feel so good and wonderful because you didn't hurt a thing. Meanwhile those frozen mice were either frozen while alive or as most mice providers will tell you "Killed Humanly using CO2, which makes all the F/t pro people push their stupid "humane theory"
CO2=Carbon Dioxide, also known as "CO2" and "The Silent Killer", is produced when we exhale. Our bodies convert oxygen, to carbon dioxide, as do all animals.
Studies on on mice, monkeys, and humans have shown one undisputed fact: direct correlation between exposure to pure Carbon Dioxide, and slow, agonizing death.
CO2 is colorless and odorless. :bang: Symptoms of exposure include dizziness, shortness of breath, inability to focus mentally, and death.
"imagine being able to breathe except every next breath you seem to choke more, as the co2 molecules bond with your blood instead of oxygen. This takes from 5seconds to 2 minuets(makes it look humane on rats/mice because unlike people and dogs there aren't many VISIBLE pain characteristics) My King and my corns average a kill in 5-10 seconds. Both are horrible ways to die! However my snake has never taken 2 minuets!!!!! So in my opinion based of the 4 snakes i own its a quicker death with the snake. I myself was an AVID f/t ONLY feeder, Especially because one of my fav pets is a fancy mouse, until i actually researched methods of killing f/t. Its not a magic gas that puts them to sleep easily and calmly, which for some reason because of that FAKE "Humane label" people argue and preach.
In conclusion (MY OPINION ) I feed both because personally i don't care about mice nor will i ever place a rodent(responsible for Unmanageable deaths to people, from disease)on the same tier as a HUMAN. BUT BUT BUT logically a snake is more (only using this word because thats whats debated) HUMANE than a CO2 Gas chamber.! And until someone posts a Chemical compound used thats proven to be PAINLESS like "morphine"(which with the proper dosage will kill) That all these f/t providers start using, its ignorant to say f/t frozen mice are more humane! When its MASS SUFFERING!
(ONCE AGAIN I MYSELF FEED FROZEN mainly due to convenience and i don't believe in Terms like "humane" should even be used with rodents) The whole reason for the Human Theory rite up was I'm tired of people who have no idea how the GAS works always pushing that its better for them its better! )
