Feeding & Water:
Corn snakes eat 1 frozen/thawed mouse every 7-14 days, from pinkies to large mouse depending on the size of the corn snake. A large bowl of tap water should be present in their enclosure and will need to be replaced every day. Corn snakes are very easy to feed and almost never refuse a meal. Firstly, the easiest way to gauge what size mouse is needed is by comparing the girth of the mouse to the girth of your snake’s belly. The mouse should be about the same size around, or a touch larger. If you feed them a mouse equivalent to this size, feeding once a week is ideal. Because corn snakes vary in size, there is no exact food size to follow. A hatchling Corn Snake is best eating pinky mice, while adult corn snakes usually need adult or large mice. All mice should be “naturally” de-frosted by leaving them for a few hours (do NOT place in a microwave or in boiling water to speed up the thawing process).
Simply hold the mouse with snake tongs to avoid your hands being mistaken for food and shake the mouse around the head of your snake until it strikes and grabs the rodent. Avoid sudden jerks with the food after it’s been bitten. Pulling the mouse too hard could result in your snake losing a tooth, which is not only a waste of a mouse but very demanding on your snake’s body to vomit up. Wait 24 hours before handling and because Corn Snakes are crepuscular, feed your corn snake at the last part of the day.
A water dish is also necessary, and the water should be kept meticulously clean. Snakes often defecate in their water, and when this happens, the waste should be cleaned immediately. A heavy dish several inches in diameter makes a good water source. you may find your snake soaking in the dish, particularly before a shed.
