Sometimes when they take a mouse they will want nothing to do with a rat ever again. This can become a pain when the snake is bigger and you have to feed 5-6 mice a week. If I had a snake eating rats it would never get again. I made that mistake before now I can't get her to have any interest in rats but if your snake will switch back and forth I can't see a problem doing it.
I have a big female close to 1800 grams who only eats mice. It is a pain in the but.
