Many snakes eat fish, fresh or frozen, which can also be purchased. Frozen fish should only be used when fresh fish is not available. There has been much evidence suggesting that a natural diet is the best for a snake in captivity. Snakes need to eat at regular intervals. Ones that are smaller than three feet should be fed prey the size of a mouse once or twice a week.
Larger snakes take larger prey at less frequent intervals.
Force feeding a snake should be a last resort. They will swallow a food item if it is placed far back in its mouth. Caging of snakes Types of cages can vary as much as the varieties of snakes themselves, simple or extravagant. Caging snakes is very much a matter of individual preference. Many smaller snakes can thrive quite nicely in a ventilated plastic shoe or sweater box.
