Corn snakes are widely regarded as the best introductory snake species. Native to North America, they are generally docile, reluctant to bite, come in hundreds of beautiful colour variations (morphs), and are excellent eaters. A healthy corn snake can live for 15 to 20 years, making them a long-term commitment.

Vivarium Setup & Size
Corn snakes are active, inquisitive snakes that enjoy exploring and climbing.
- Size: An adult corn snake (which can reach 4-5 feet in length) requires a wooden vivarium measuring at least 120cm x 60cm x 60cm (4ft x 2ft x 2ft). Starting a tiny hatchling in a massive enclosure can sometimes stress them, so many owners start with a smaller setup (e.g., 2ft) and upgrade as the snake grows. Ensure the enclosure is 100% escape-proof—snakes are master escape artists.
- Substrate: Aspen bedding, Lignocel, or orchid bark are excellent choices, allowing the snake to engage in natural burrowing behaviours. Avoid pine or cedar shavings, as the aromatic oils are toxic to reptiles.
- Decor: Provide tight-fitting hides at both the warm and cool ends. Add sturdy branches for climbing, and artificial foliage for cover.
Temperature & Humidity
Like all reptiles, corn snakes need a temperature gradient to thermoregulate, moving between warm and cool areas to digest food and maintain health.
- Heating: A Deep Heat Projector (DHP) or a Ceramic Heat Emitter (CHE) is recommended to heat the ambient air. Alternatively, a heat mat covering no more than a third of the floor can be used. All heat sources must be controlled by a thermostat. If using an overhead bulb, it must be covered by a wire guard to prevent the snake from wrapping around it and suffering severe burns.
- Temperatures: The warm end (basking area) should be around 29–32°C (85-90°F). The cool end should sit between roughly 21–25°C (70-77°F).
- Humidity: Corn snakes thrive in moderate ambient humidity of 40-60%. Provide a large, heavy water bowl at the cool end (large enough for the snake to soak in). To aid shedding, you can provide a “humid hide” filled with damp sphagnum moss.
Diet: Feeding Guide & Mouse Sizes
Corn snakes are strict carnivores. In captivity, they are fed a diet of entire, commercially bred, frozen-thawed mice. You should never feed live prey in the UK; it is unnecessary and dangerous to the snake.
The Golden Rule of Sizing: You should feed a mouse that is roughly the same width (or up to 1.5x wider) than the thickest part of the snake’s body.
Typical Feeding Schedule:
- Hatchlings: 1 “Pinky” mouse every 5-7 days.
- Juveniles: Move up gradually to “Fuzzies,” then “Hoppers,” feeding every 7-10 days.
- Adults (2+ years): 1 Adult mouse (or large/ex-breeder mouse depending on the snake’s girth) every 10-14 days. Feeding an adult every week will lead to obesity.
Feeding Best Practices:
- Always thoroughly defrost the mouse at room temperature or in warm water. Never use a microwave.
- Offer the prey using long feeding tongs.
- Do not handle your snake for 48 hours after feeding. Handling them too soon can cause stress and dangerous regurgitation.
Shedding (Ecdysis)
As your snake grows, it will shed its skin periodically. You will notice their eyes go cloudy or “blue” a few days prior. During this time, they will likely hide and refuse food. Once they shed, check that it came off in one entire piece, paying special attention to the tip of the tail and the eye caps.
