Is It Time To Move Up Food Size?

[RoseRed]

I am always conservative when it comes to moving up food size. My BRB ways 805g and she is on small rats (around 60g) right now and I am about to go feeder shopping and I am wondering if I should buy medium rats. I know about the 1 1/2 width rule, but I am not good at judging it unless the snake is right next to the rat (and we know what would happen if the rat got that close to the snake). Is there an wight ratio between snake and feeder size?

She has been taking down small rats easily.

Med. should be fine. My guy was taking mediums around 600-700g no problems.
