You should feed your snake about once a week. Do not give your snake a mouse that is more than 1 ½ times the width of his mouth. If there is a large bulge in the snake after eating, the mouse was probably too big. Better to give two smaller mice than one large. There is a bit of debate as to which mouse is better – alive or dead. If your snake will eat it, most agree that dead is best. Live mice can bite your snake and seriously damage it.
You can purchase frozen mice online and store them in your freezer. Just be sure to tell the spouse before he heats up a mouse surprise! Purchasing frozen mice online is actually cheaper than buying live mice that you kill on your own, saving you about $1.50 a mouse. If your snake regurgitates his food, the tank is probably too cold. Snakes digest better in warmer temperatures.
