I just feed f/t so I don't really know how to go about pre-killing prey. It never hurts to try feeding pre-killed or f/t. When I got my first BP the petstore told me she only ate live mice so that's what I fed for a while, but then I tried a f/t rat and she took it no problem. You just never know what they are going to do.
If the Neosporin doesn't say pain-relieving then it should be fine.![]()
