[header] How to feed a snake [title] Purchase mice or rats. [step] In the wild, most snakes eat mice, rats, or other small rodents. These animals meet all of snakes' nutritional needs, so an all-mice or all-rat diet is completely sufficient to keep your snake healthy and happy. 
If you have just one snake to feed, you can purchase mice or rats from a local pet store. If you have a large number of snakes, you might consider breeding mice or rats for feeding purposes.
