A quieter house is not automatically a calmer one for a rescued iguana. At the rescue centre the noise was constant — doors, voices, cleaning routines at fixed hours — and constant noise becomes predictable noise. Your home is quieter overall, but its sounds arrive without warning: a doorbell, a vacuum starting up, a dog barking two gardens away. For an animal that runs on routine, the change itself is the stress, so the first weeks are about making your quieter home predictable rather than simply peaceful.
Copy the centre's routine before you improve it
Ask the rescue centre exactly what his days looked like: when the lights came on, when food arrived, which greens he actually ate, how keepers approached the enclosure. Then reproduce that pattern at home for the first fortnight, even where you plan to improve on it later. Offer the same leafy greens — collard, mustard and dandelion greens are iguana staples — at the same times of day, and keep handling to essential health checks only. Familiar food at familiar times tells a wary iguana that this new place follows rules he can learn.
Set the enclosure up as a lookout, not a hideaway
Place the enclosure in a low-traffic room where he can watch household life from his basking shelf without being its centre — the corner of a living room usually works better than a spare room he rarely sees anyone in. Hold the warm end steady with a basking spot around 95°F and a cooler end in the high 70s, keep the light cycle to a consistent twelve hours, and mist or soak him to keep humidity up, since dry indoor air dries a rescue iguana's skin and suppresses appetite. Approach slowly, talk before you open the door, and always let him see your hands coming.
Let contact be his idea for the first weeks
Once the routine has held for a week or so, open the enclosure door during his active morning hours and sit nearby reading, letting him choose whether to come closer or stay put. Short, calm sessions build more trust than daily lifting sessions he cannot escape, and a piece of his favourite green offered by hand after he has approached teaches him that people predict good things. Change only one variable at a time afterwards — a new food, a new room to explore, a first bath — with several settled days between changes, so if he goes off his food you know which change caused it.
The signs that mean a vet call, not more time
A rescued iguana who hides for the first few days and eats lightly is behaving normally; the picture changes if he has eaten nothing at all after a week of consistent routine, stays dark-coloured and limp rather than alert, or develops swelling around the jaw, discharge from the mouth or nose, or shed skin stuck fast over the toes and tail tip. Those are the points to stop waiting and book a reptile vet, taking the centre's notes on his history with you. When his profile travels with him into your care on KinsLe, Transferrable Profiles means those rescue notes, his foods and his settled routine are already in one place for whoever needs them next.
