My question is if you feed f/t and have been doing it for your snake or snakes for a while, how important is it to give the feeder a bit of a shaking, you know by grabbing the feeder tail or leg and shaking it after the snake has wrapped up the feeder. I've seen video's where people do this to make the snake feel like the f/t was live so they shake the bitten and wrapped feeder. Is this important to keep doing this or is it just a waste of time and the snake doesn't care if the rat/mouse is dead already especially if it has been eating f/t for several months or more. People with a lot of snakes do they take the time to shake the wrapped up feeder. I ask this question because I usually feed when it's pretty dark in the room ( an infra-red light in the room light socket at best ) and I would rather just skip the shake the wrapped feeder part.
