Overview

  • The California kingsnake is one of the more forgiving beginner snakes, tolerant of minor husbandry errors and reliably tame with regular handling.
  • It is bred in many colour and pattern morphs and is widely captive-bred, so wild-caught animals are not necessary.
  • Kingsnakes are bold, active foragers that explore their enclosure and feed readily.
  • This makes them a good first snake, but their strong appetite means they must always be housed alone, as they will eat other snakes.

Housing

  • An adult needs a secure enclosure of at least 120x45x45cm with a tight-fitting, escape-proof lid, as kingsnakes are strong and persistent.
  • Provide a substrate deep enough for burrowing, such as aspen, plus two hides (one warm, one cool) and some sturdy decor.
  • Set up a thermal gradient with a warm side of 28-30C and a cool side of 22-24C, controlled by a thermostat.
  • UVB is beneficial but not essential.
  • Keep a large bowl of fresh water available at all times.

Diet

  • Kingsnakes are carnivores fed appropriately sized frozen-thawed rodents, roughly the width of the snake at its thickest point.
  • Hatchlings take pinky mice; adults take adult mice or small rats every 7-14 days.
  • Thaw food fully and warm it to encourage a reliable feeding response, and use tongs to keep the snake's strike directed at the prey rather than your hand.
  • Overfeeding causes obesity, so reduce frequency as the snake matures.

Health

  • Kingsnakes are robust but can develop respiratory infections if kept too cold or damp, and scale rot in dirty, wet enclosures.
  • Incomplete sheds usually point to low humidity or dehydration.
  • Maintain humidity around 40-60% and offer a humid hide during shed cycles.
  • Mites can arrive on new animals, so quarantine new arrivals.
  • An annual reptile-vet check helps catch problems early.

Temperament

  • California kingsnakes are generally calm and tolerate regular, gentle handling, becoming noticeably tame over time.
  • Some are strongly food-motivated and may strike when they smell prey, so wash your hands before handling.
  • They may musk or vibrate their tails when startled but rarely bite defensively once used to people.
  • Keep sessions short and avoid handling around feeding times to build trust.

A good fit for

  • First-time snake keepers
  • Keepers wanting an active, visible snake
  • Those seeking a hardy, low-cost pet
  • Morph collectors

Common mistakes to avoid

  • Never house two together - cannibalism
  • Escape-proof lid is essential
  • Overfeeding leading to obesity
  • Food-response strikes if hands smell of prey
