Well I don't want to go down that road. If I can continue feeding frozen/thawed I want to continue down that road not only for Snickers' safety but for my well being as well! I don't think I could watch Snickers "kill" a mouse or rat.
I have RESCUED mice from being killed by cats before with my own hands. My friend had a very nice half million dollar house but he did have a mouse problem and he had a cat that killed those mice. Twice I was there and his cat found mice and got them them and played with them and the mice "played dead" instinctively and I scooped up those mice both times and ran outside a few blocks and then opened my hands on the ground and they bolted!(Everyone was amazed by my tenacity...though I'm pretty sure that cat hates my guts! Tough luck for the cat. Go eat your cat chow!)
I love all animals except for insects and arachnids(YUCK!)
Anyway I would have a difficult time feeding live prey to Snickers because not only would I worry about her safety doing so but It's just easier for me to feed prey that is already dead anyway.
