6-24 months
Sustained growth; large mouse/rat every 7-10 days; sturdy branches; watch for complete sheds and eye caps.

Care
Vivarium: minimum size depending on species (consult species-specific guides). UVB essential for diurnal species.
Temperature: day/night gradient · warm zone vs cool zone for thermoregulation.
Humidity: depending on species (rainforest 70%+ · desert 30-50%).
Feeding: species-specific diet · insectivores, herbivores and carnivores vary radically.
Veterinary care: an exotics vet (a regular vet will NOT do). Annual check-up.
Care in detail
🍽️ Nutrition
Carnivore: dead rodents or small rabbits sized to the snake, every 1-3 weeks (adults every 2-4 weeks). Do not overfeed: obesity is common in captivity.
✂️ Grooming
