Its not like we put the rats in the same container as the meat we use for food.
I double bag mine and put it on a side shelf in the freezer.
There is no right or wrong answer to the f/t vs. live conversation. One is not better then the other. If your snake only eats live, feed it live, if your snake only eats f/t, feed it f/t. If your snake will eat anything, then it is your choice.
Getting the snake to eat is first priority, your feelings and wants come after.
I don't like feeding live. I don't like taking care of animals that are going to be food, especially if I get a refusal (which I rarely do with live). I prefer f/t because it is easier for me and all my snakes will eat f/t with no problems. If I had a snake that would only eat live, I would get it live food.
