The advantages are only available if you're able to offer F/T the OP however is not so their two options are #1 Feed live or #2 don't get a snake.
..I offer both live and F/T..
To me the Live V. F/T debate has always been pointless..Do what works for you and your animals..If that means dressing the rats in dresses and high heel shoes so be it..But trying to debate what works in one persons collection vs another is as pointless as debating which angle is the best to view a TV from.
The world Snake World will forever go rounds and rounds trying to convince each other that one way is better than the other, Me I'm going to focus on my snakes and what works for them..
To the OP..I hope you enjoy your new little one and not to worry feeding live isn't going to cause the Robot Nazi Zombie Apocalypse..You'd do fine..
