Yes, but I stay close by. I go through and feed everyone but stay in the room the whole time. My tubs are semiclear so I can observe what is going on. If the snake has not got it within 15 minutes or so I take it out. With exceptions of a couple that really like to hunt. They may take longer but through experiences I know who hunts and who don't.
I keep a record of who got what kind of feeder. Then in 30 minutes to an hour I go back and check I mark who ate and the non eater get put back till next week.

Always watch the strike...That is when rats can get a good bite in if the snake does not get them in the right spot. I keep tongs in hand and stick it in the rats mouth if it can get its head to the snakes body.
