Feeding Issues

Hey everyone, My BP has stopped eating for some reason, The last time she ate was 3 weeks ago, and she ate a small rat for the first time, I have tried to feed her since but she refuses to eat.
My temps are all good and my humidity is at 55 %, nothing has changed, she will go right up to the rat but will not strike, I thought maybe she was starting a shed due to her eyes being white but I'm not sure this is the issue.
please help, I know they can go for long periods of time without eating but this worries me.

BP refuse for for various reason, seasonal, breeding, catching up, the wall because that's what BP do.

It can last from a few weeks to few months, what you need to do is assess your husbandry see it is is optimum, stop all handling, downsize the enclosure if necessary, make sure your animal is well hydrated and most importantly be PATIENT.

How big is your BP?

How old and how large is she? If her eyes are cloudy she may be prepping for a shed. If your temps and husbandry are dialed in, and your snake isn't losing a significant amount of weight or showing obvious signs of illness, I don't think you have anything to worry about just yet.
