Corn snakePantherophis guttatus

Corn snakes are slender, active colubrids from the south-eastern United States. They come in a huge range of colours, are usually reliable feeders and are a great first snake.

Enclosure

Adults need at least 120 × 60 × 60 cm (4 × 2 × 2 ft). A good rule: as long as the snake, half as wide and at least 60 cm tall. Corn snakes climb, so taller is welcome.

House singly.

Heating

Provide a basking surface around 32°C (90°F) with a cool zone of 24–27°C. Heat can go off at night for adults, but keep hatchlings warmer.

Always use a thermostat.

Lighting & UVB

UVB benefits corn snakes: aim for a UVI of 2.0–3.0 in the basking area, on a 12-hour day. Replace tubes every 12 months.

Humidity & water

Average humidity of 65–75%. A humid hide helps with shedding.

Keep a large, heavy water bowl in at all times and change the water daily.

Substrate & decor

Use a burrowing-friendly substrate such as a soil mix or aspen. Add at least two hides (warm and cool), branches to climb and plenty of cover.

Diet & feeding

Feed frozen-thawed mice or small rats about 1–1.5 times the width of the snake's thickest point.

Hatchlings: every 5–7 days. Juveniles: every 7–10 days. Adults: every 14–21 days.

Thaw prey in the fridge, then warm it in a sealed bag in warm water before offering with tongs.

Supplements

Whole prey covers most needs. A light, occasional dusting with an all-in-one calcium and vitamin supplement is optional.

Handling

Corn snakes are usually docile. Wait 48 hours after feeding, and support the body rather than gripping.

Health watch

Watch for stuck shed, mites, respiratory infection (wheezing, bubbles at the nose) and regurgitation.

Every animal is an individual. Use this sheet as a starting point, measure temperatures and UVB properly, and speak to an exotic vet about any health concerns.
