I had a doe have her first litter on the wire one warm morning. As each kit came out and crawled about a raccoon got each leg as it came through the bottom wire and pulled it off.
Even legless my first reaction was how to make them better instead of kill them quick.
The nurturing instinct is VERY STRONG!!! So killing a helpless baby is hard to do, even when there is no other thing to be done.
Hand help pruners work great if they are a little blunt, one snip behind the head and the spine is severed but the skin is still intact so no blood.
Having had many snakes over the years most will take dead prey but some will starve to death without the stimulation of live prey. The only thing wrong with feeding live prey to a snake is making a joke or game of it, the snake is just doing what comes natural to it really. We had a grey rat snake get into a purple martin house once, it ate the entire bottom level clean, every baby bird it could stuff into itself. I had to get between the snake and the other employees at the garden center, they wanted to slice and dice it because it "Ate helpless baby birds!" :roll:
