Do not dangle. That puts the feeders into a panic. Panic and scared animals are dangerous and your chances of a bite from them increases.
You want your feeders calm. Just gently place the rat in the enclosure and keep watch. A calm feeder will either curiously explore or sit and groom itself.
If your snake strikes and gets a bad hold where the rat's teeth are in position to bite, just shove a pen/chopstick/tongs into its mouth till its dead.
Hundreds of live feedings here and no wounds on my snakes. Just make sure youre you're feeding an appropriately sized prey. So prey not overly large.
