in my case, as far as hassle goes,
i prefer to just put a live mouse in the tub and watch to make sure its killed, and that my snake begins to swallow it.

with f/t, u hafta wait for warm water, then put a mouse in a baggie, let it sit for 10 mins or w/e, take it out, i dry mine with a hairdryer so they're not soaking, then offer, and wait til snake swallows..

just takes longer. although with responsible and knowledgable live feeding, even a .00000000000000000000001% risk of a scratch or bite, i dont like. it may not do any harm at all, but i like my snakes scales the way they are ^-^. i hate taking the chance
