Corn snake care

Pantherophis guttatus

Short answer

Corn snakes come from the USA. They grow to about 150 cm (about 5 ft) and live around 10–15 years[1]. The RSPCA sets the basking zone at 28–30°C (82–86°F), the cool end at 20–24°C (68–75°F) and humidity around 40–50%[1]. Hatchlings start on one pinky mouse every five to six days; adults eat one adult mouse every seven to 14 days[1].

What kind of snake is it?

Corn snakes come from dry scrubland and forest in the USA, and take their name from turning up in and around corn barns hunting rodents[1]. They live mostly on the ground, hide in burrows and under logs, climb well, and are most active at dawn and dusk[1]. They are non-venomous constrictors and come in many colour and pattern morphs[1].

Enclosure

Corn snakes need room to stretch out fully, and the RSPCA notes they prefer larger enclosures and are more active in them[1]. Rule of thumb: at least the snake's length long, and a third of its length wide and high. A 150 cm snake needs at least 150 × 50 × 50 cm (about 59 × 20 × 20 in)[1]. Hatchlings can be stressed by a big space, so start small and size up, or fill a larger enclosure with small hiding spots[1].

Give at least two hides, one at each end, plus a humid hide with damp moss, and branches or climbing boards[1]. For substrate the RSPCA suggests reptile soils or soil and sand mixes, with paper towel only as a temporary option while you monitor a new snake[1]. VCA's vets lean toward paper or artificial turf because it is easy to clean[2]. Both are defensible; whatever you use, keep it clean.

Heat and light

Basking zone 28–30°C (82–86°F), cool end 20–24°C (68–75°F)[1]. For a small hatchling setup, a heat mat under one side works, run on an on/off thermostat set at 30°C (86°F)[1]. In a normal home you can switch heat off at night and let it drop to 16–20°C (61–68°F); if your room gets colder than that, add a non-light heat source on a thermostat[1].

The RSPCA recommends a low-output UVB tube with a gradient from UV index 1.0 at the basking spot to zero in the shade (lower for albinos), on a 12-hour timer[1].

Feeding

Feed dead mice: one pinky every five to six days for a hatchling, working up to one adult mouse every seven to 14 days, each about as wide as the widest part of the snake[1]. Weigh regularly so you catch a snake that is getting thin or fat[1]. No supplements are needed if the prey is good quality[1].

Handling

Corn snakes can get used to regular handling[1]. Support the whole body, keep sessions to around 10–15 minutes, and wait 48 hours after a meal[1]. If the snake pulls its neck into an S shape, it feels threatened; put it back and try another day[1]. House them alone[1].

Health watch

  • Blisters on the skin can mean the enclosure is too damp[1].
  • Small black specks on the snake or around the water bowl, or long soaks, can mean mites[1].
  • Abnormal droppings can be a sign of internal parasites[1].
