Yes but the mouse seed mix is JUNK. It's is only filler and fat. Get some lab blocks or get some hog feed(non-medicated) and mix that with cheerios, Total, crispy rice, puffed wheat, puffed rice, dry tri-colored pasta, oatmeal, small amount of high quality senior dog food, and maybe some black oil sunflower seeds. That will be a much higher quality diet for the mice than that seed mix junk from the pet store.

Remember, your snakes are what they eat. If they are eating crap, they will reward you will crappy growth.
