  3. Humidity: Maintain moderate humidity levels of 40-60%. Mist the enclosure as needed, especially during shedding periods, and provide a humid hide with moistened substrate.
  4. Substrate: Use safe substrates such as aspen shavings, cypress mulch, or paper towels. Avoid substrates that can cause impaction, such as sand or cedar shavings.
  5. Feeding: Offer appropriately sized prey items, typically mice or rats, every 7-10 days for juveniles and every 10-14 days for adults. Adjust feeding frequency based on the snake’s age, size, and activity level.
  6. Water: Provide fresh, clean water in a shallow dish at all times. Ensure the dish is large enough for soaking, as corn snakes may soak to aid in shedding or hydration.
  7. Handling: Handle your snake gently and avoid excessive handling, especially before and after feeding. Wash your hands before and after handling to prevent the spread of bacteria.
  8. Health Monitoring: Monitor your snake’s behavior, appetite, and appearance regularly. Look out for signs of illness, such as lethargy, weight loss, respiratory issues, or abnormal shedding.
  9. Veterinary Care: Schedule annual check-ups with a reptile veterinarian and seek veterinary care promptly if you notice any health concerns. Follow their recommendations for vaccinations, parasite prevention, and treatment.
  10. Enrichment: Provide environmental enrichment such as branches, rocks, and foliage for climbing and hiding. Rotate and change enrichment items regularly to prevent boredom.
  11. Cleanliness: Spot clean the enclosure daily and perform a thorough clean-out every few weeks. Disinfect the enclosure and accessories regularly to prevent the spread of pathogens.

By consistently meeting these care requirements and providing a suitable environment for your corn snake, you can help ensure its long and healthy life in captivity.
