This guide concerns the corn snake, Pantherophis guttatus. It is not a feeding or environmental plan for every snake species. Have the enclosure ready and checked before bringing the animal home.

Space, security and choice

Choose an enclosure long enough for the snake to straighten its whole body. The RSPCA also allows at least one-third of its length for both width and height: its example for a 150 cm corn snake is 150 × 50 × 50 cm. Size for the adult, and upgrade as growth requires.

Keep one snake in a secure, ventilated enclosure. Provide sheltered retreats at the warm and cool ends, cover for a young snake and stable climbing opportunities. A large bare box does not supply the security of a furnished enclosure.

Measured conditions

Use guarded heat, a suitable thermostat and independent thermometers. Check both ends and distinguish an air reading from a surface reading. Agree a consistent daytime and nighttime plan with a reptile-experienced vet rather than combining incompatible care-sheet figures.

The RSPCA’s normal humidity reference is around 40–50%; a separate humid hide provides a local moister retreat. Use a hygrometer and ventilation rather than making the whole enclosure continually wet. Provide suitable low-level UVB with shade, following the fixture’s distance and replacement guidance.

Food, water and welfare

Offer appropriately sized whole rodent prey supplied pre-killed, using fully thawed frozen prey where applicable. Never offer a live rodent: it can seriously injure the snake. Use feeding tongs and follow safe supplier instructions for preparation.

Provide clean water, remove waste promptly and wash hands after care. Record weight, appetite and shedding. Persistent food refusal, weight loss, injury or abnormal breathing needs veterinary assessment; do not improvise force-feeding.
