How long do Milk Snakes live?
Milk snakes live 15-20 years in captivity and reach 2-4 feet (60-120 cm) depending on subspecies, weighing 200-900 grams as adults.
What do Milk Snakes eat?
They are carnivorous constrictors feeding on frozen-thawed mice: pinkies for hatchlings progressing to adult mice. Feed juveniles every 5-7 days and adults every 7-14 days, one appropriately sized prey item (no wider than the snake's body). Never feed live prey (injury risk) and never feed another snake. No vegetables or insects.
Milk Snake enclosure setup
A single adult needs a 20-40 gallon terrarium with a secure lid. Provide a warm side of 82-85°F (28-29°C) via a heat mat/ceramic, a cool side around 72-75°F (22-24°C), and a night drop to 68°F (20°C). Humidity 40-60% with a water bowl; a humid hide helps sheds. UVB is not required (nocturnal), though a low light is harmless. Always supply at least two hides.
Common mistakes with Milk Snakes
Key errors: housing two snakes together (kingsnakes cannibalize cage mates), feeding live prey (bites and infections), prey sized too large (regurgitation/impaction), and no temperature gradient (poor digestion).
Beginner mistakes to avoid
- Cohabiting — milk snakes are kingsnakes and will eat cage mates.
- Feeding live prey — rodents injure and infect snakes.
- Oversized prey — regurgitation and impaction.
- No heat gradient — poor digestion and weak immune system.
