Green iguanas are gorgeous and impressive, but they grow huge — over five feet — and need a custom room-sized enclosure, powerful lighting, and confident handling. They're an advanced, long-term pet that many people sadly underestimate, so they're only for very prepared keepers.

How to care for your Iguana
🏡
HomeA custom, room-sized enclosure with powerful UVB, basking heat, climbing branches, and humidity.
🥗
Food & waterA fully plant-based diet of leafy greens and veggies — no animal protein.
🩺
HealthA reptile vet, strong UVB, warmth, and careful handling as they grow large and strong.
🤲
Handling & playDaily calm handling from young helps; adults are powerful and need an experienced keeper.
🤧
AllergiesNo fur or dander, so allergy-friendly. Wash hands — reptiles can carry salmonella.
Green iguanas are big, long-lived lizards — they can reach 5–6 feet and live 15–20 years. They need a lot of space and care, so they're best for dedicated families.
✅ Before you bring an iguana home
🏠
Room at homeIguanas grow large and need a custom, room-sized enclosure as adults, with tall climbing space, strong UVB, and warm basking temperatures. Plan for that big space from the start.
🛒
Supplies to get firstGet a large (and eventually huge) enclosure, strong UVB and basking lights, thermometers, sturdy climbing branches, a big water area, and a fresh-greens diet (iguanas are vegetarians).
🩺
Finding a vetIguanas need a reptile or exotic vet experienced with big lizards. Find one before you commit (ARAV.org), since they're prone to issues without perfect lighting and diet.
🛡️
Pet insuranceIguanas are a long, big commitment and care can be expensive. Exotic pet insurance is worth considering; either way keep a solid emergency fund and get the UVB and diet right.
🗓️ Your routine — easy chores to remember
☀️ Every day
Fresh greens and water
Check basking temperature and UVB
