Reptile keeping experience: beginner

Below are the basics for keeping corn snakes.

Cage:  Hatchlings can be housed in 10 gallon aquariums or similarly sized specialty reptile cages. Adults should be kept in cages with a footprint of at least 30" x 12".  They are terrestrial so a larger floor area is preferred over climbing height.  A screen lid should be used on top of the cage.

Accessories: A hide box/shelter should be provided to allow them a place to rest.  Corn snakes are fairly active so climbing branches, rocks, and logs are appreciated.  A water bowl large enough for the snake to submerge is suggested.  A thermometer and humidity gauge should be used to monitor cage conditions.

Humidity: Humidity should be maintained between 30-40%.  If this humidity is not achieved with the water bowl alone, you may need to mist the cage and substrate 1-3 times daily during the shedding period.  If the snake is having issues shedding, place moist sphagnum moss in the hiding area.

Substrate: Many choices are available and the most common include cypress mulch, fir bark, aspen, and cage carpet.  A layer of substrate 2-3" deep may be appreciated. 

Lighting/Heating: The main source of heat should be an under tank heater or some form of belly heat.  Snakes are more comfortable absorbing heat from the ground rather than from above.  Place the under tank heater on one end of the tank and keep any lights on the same end of the enclosure as this allows the snake to thermoregulate.  It is important to create a hot side and cool side in the tank so do not place heating and lighting in the center of the enclosure.  Corn Snakes do not require UVB lighting.  A daylight bulb is important to provide a proper photoperiod.  Be sure the daytime bulb is off at night so you do not disrupt the day/night cycle.

Temperature: Provide a range of temperatures in the enclosure with a hot spot of 85-88°F.  This can be accomplished with an under tank heater, an incandescent basking light (or heat emitter) or a combination of both (as described above).  The cool end of the enclosure should be 75°F and nighttime temperatures can drop to 70°F.     

Diet/Feeding: Corn snakes can be fed appropriately sized mice and rats their entire lives.  Be sure to feed prey that is no larger than the widest part of the snake. There should never be a bulge after the snake eats.  Babies and juveniles should be fed every 7-10 days. Adults can be fed every 7-14 days.
