I am a breeder and have over a hundred animals. Most of the rats i breed here, as well as ASF's and Gerbils for those picky females. I have not been successful in breeding mice, so I buy them generally. I feed only live rats that are a few weeks old, I have to feed more, but they are not aggressive. That is until a snake strikes and misses. I feed in cycles, and do average 30 or so at a time, and one type of rodent at a time. I have a full time job, so to feed f/t would literally take all of my time.

So, with that said, the scariest thing is with the mice and the smaller snakes. Mice are the most aggressive. I keep a kibble of food in to preoccupy the mouse, and keep an eye on all at the same time.

Yes, the bites that come from being coiled happen, and one has to watch for that. But I have yet to get serious injury.
