Or you could be humane and use co2 since selling splatter rats to people might turn you off after splattering hundreds of them in a bag
I breed pet rats and feeders, it's not that big of a deal really, you just don't attach yourself to food.
Have you had one that actually splattered? I've never even seen a drop of blood with the whack in the bag method.... just quick and clean with no suffocation required.
