Am I Ready for an Iguana?
An iguana is the animal this site most often steers people away from, and not because they are unpleasant. It is because the hatchling in the shop becomes a large, strong, long-lived lizard that needs a custom enclosure most homes cannot accommodate, and almost nobody buying one has pictured that animal rather than this one.
The 6 questions worth answering honestly
Work through these before you decide rather than after. There are no wrong answers and a "not yet" is a perfectly good result — it usually means one fixable thing stands between you and a pet you would do well by.
Baby iguanas look small — but adults grow 5–6 FEET long and eventually need a closet-sized (or room-sized!) enclosure. Can your family commit to that?
- Yes — we know and we've planned the space
- We have a big tank, not a room
- SIX FEET?!
If that one gave you pause: Look at photos of adult iguanas next to people, then look at your house with a grown-up. This is the #1 reason iguanas get given up.
Iguanas live 15–20 years and need fresh chopped greens EVERY day (they're vegetarians!). Daily salad duty for two decades?
- Daily salad chef for 20 years — yes
- That's a long time
- Probably not honestly
If that one gave you pause: Practice making a fresh "iguana salad" daily for two weeks — collard greens, squash, no lettuce-only shortcuts!
An untamed iguana has a whip tail, sharp claws, and a strong bite — taming takes months of calm, experienced handling. Have you kept reptiles before?
- Yes — several, and I know the risks
- One easier reptile
- This would be my first
If that one gave you pause: Iguanas are expert-level. Spend a few years with a beardie or skink first — seriously, it makes all the difference.
They need strong UVB, high heat, and humidity — a mini tropical zone maintained daily. Can your family build and run that?
- Yes — we've researched the full setup
- Partly
- No idea what's needed
If that one gave you pause: Research adult iguana enclosures with a grown-up — many owners end up building custom ones from scratch.
Is every grown-up in the house genuinely on board with a dinosaur-sized lizard for 20 years?
- Full family yes — eyes wide open
- Some hesitation
- Not discussed yet
If that one gave you pause: This decision needs a full family meeting — an adult iguana affects everyone in the house, every day.
Why an iguana?
- I love reptiles and want a deep, long project
- They look awesome
- Saw one online and want one now
If that one gave you pause: "Looks awesome" fades; daily salads for 20 years don't. Volunteer at a reptile rescue first to test your love!
The part people underestimate
Adult size, and how quickly it arrives. The cute green lizard grows into something well over a metre long with a powerful tail and claws, needing a purpose-built space closer to a wardrobe than a tank. Rescues are full of them. If you take one on, you are committing to building that space — not to a vivarium on a sideboard.
Who an iguana suits — and who it does not
Right for you if you have genuinely planned the adult enclosure, you have experience with large reptiles, and you can commit for fifteen to twenty years. Kept properly by someone prepared, an adult iguana is an impressive animal.
Probably not for almost everyone else, and especially not as a first reptile or a pet for a child. If the appeal is a big, striking lizard, a bearded dragon or a blue-tongued skink gives you most of that in an animal a normal house can hold. Several places also restrict them outright.
What an iguana actually costs
Running costs land around $40–$90 a month once you are set up, on top of the one-off cost of housing them properly. The setup is usually the number that surprises people, not the animal. And it is not a short bill: expect 15–20 years of it. Our pet cost study compares the running cost of all 50 pets side by side if you want to sanity-check the number against the alternatives.
Questions people ask before getting an iguana
Should I get an iguana?
Usually not. Unless you have already planned and can build the adult enclosure, a bearded dragon or skink gives you the same appeal without the outcome that fills rescues.
Are iguanas good pets for kids?
No. Adults are large and strong enough to injure, and they need experienced handling rather than enthusiastic handling.
How big do iguanas get?
Large enough that a standard vivarium is never going to be sufficient — think custom enclosure, and think about it before you buy, not after.
If an iguana is not the one
A "not yet" is often really a "not this animal". These three ask less of a household on the things iguanas ask most — worth a look before you rule out getting a pet at all.
