In regards to Iguana heat..ofcourse they need very warm(tropical) ambient heat. Usually provided by heat lamps and basking spots. With ofcourse cooler areas to retreat to in order to thermoregulate. My question on this is which works best to promote the best digestion and food absorbsion? Lamp heat or underneath heat(tank heaters or heating pads,etc)? Or use lamp heat during the day and under(belly) heat during the night?

Also...
Here in Denver we have a fairly dry climate. My pen is open mesh and I've been having a hard time keeping thier humidity high. I've just been misting them often during the day with a squirt bottle. Is a regular humidifier recomended?

underground heat is generally considerd bad, or at least hot, i have to do it in the cold UK weather, many years and no probs
Iguanas' ideal humidity is 70-80%, but you can get by with around 40-50% with regular (2x daily) mistings. Put a pan of water under the basking light so it can evaporate and humidify the cage to get it up to 40-50% if it isn't already there.

Belly heat does better for digestion, but can run the risk of thermal burns. Of course lamps can, too, but they're easier to move away from the animal to prevent burns. I read an article about ambient basking heat from above promoting hours of basking, heating the body thoroughly to the bone and aiding digestion wonderfully. Heat from above is more normal, anyway.

Absolutely!! Keeping your iguana at tropical humidity (like above 70%) will promote better hydration through the animal and thereby better renal function over its lifetime. You probably known iguanas have a somewhat fragile renal system, they often suffer liver and kidney problems from having animal proteins in their diet... not enough humidity in their lifetime is also a major contributer to liver and kidney failure. Being super-humid will also help with shedding.

An ultrasonic humidifier can be purchased from a department store without a tremendous investment. You can put it on a timer to run in
10 minute cycles every hour throughout the hottest part of the day inhis cage. Don't run it close to when your lights turn off, it can drop the temp too much and promote mold/mildew growth if you run it late.

It's worth it for your iguana! Emotion: smile
