Looking at your other threads I see that you have made many changes in a short period of time. That alone can make a snake not want to eat.

For feeding f/t you do not need to move the snake to another bin. This only increases your odds of getting bit by a snake that is in feed mode. It also can stress the snake out by removing it from its home and putting it in a new environment at which point you then want it to eat.

In your other threads I suggested you used water to thaw the rat and then tried to feed it. How did you warm the prey up and what temp did you present it at? The body temp of a living mouse is about 100F so the f/t needs to be the same. This can be achieved by using hot water(I do it that way) but letting a prey item thaw and then serving it is not a good way to present it to your snake.

To better your odds feeding in a dark room at night works well. Make sure its quiet and the snake is not bothered by anything when it gets near feeding time. When I feed its completely dark except a red bulb in a lamp.
