I am one of those people that had this happen in 1999. Luckily my boa wasn't badly injured and it prompted me to ask on forums and that's when I found out you could feed pre-killed and later heard about frozen/thawed.
I have yet to meet a snake that I cannot convert to f/t and hopefully it stays that way.
The least amount of suffering for the prey plus cheaper, no hassle feeding for my snakies, that's how I like it.
I've even got a bunch of my ball pythons taking f/t rabbit kits which I honestly did not expect would happen.
I have enough snake species that there is always someone who can take a refused rodent if/when it happens or as others have stated, toss into a field for the local wildlife to scavenge.
