You are probobly reading this site becuase you are thinking about buying a desert iguana as a pet. they make very good pets, but you have to know how to care for them. That's why I made this care sheet. One place you can buy them is at General Exotics. Oh yeah and remenber they get to be about 12 inches in length.
I would suggest a 75 gallon tank for a single lizard, but remember bigger is always better. Try and make their cage as realistic as possible.
They're is a lot of discussion going on around wether to put sand in their cage of not. I think that sand is an excellent choice because it gives them a place to dig. I put mine on half of the cage, the oppisite side of the food and water bowls.
You will want a tempature gradient from the low 8os to the 100 degrees. The basking temp should be around 110 degrees. At night the basking and heating should be shut of and the tempature gradient be allowed to drop to around 60 to 70 degrees. You should provide UVA and UVB.
Desert iguanas are herbivorous, meaning you need to feed them primarily vegetables. Collard greens, dandelions, hibiscus, and even prickly pears (trim the spikes off).
Hibernation starts about November and ends in either Feburary or March. Slowly start dropping the tempature about halfway through October. About halfway through october turn off all heating and lighting your friend should be hibernating. At the start of Feburary you should start putting fresh water in his bowl evey day, for when he wakes up.
You will not want to handle desert iguanas until they trust. Once you get your baby or adult let it stay in its cage for two weeks. After two weeks put your hand in the cage, and remember let the animal come to you. Don't pick it up just let it get used to your hand. Do that every day for a week. Then slowly pick it up, take it about 8 inches off the ground and then put it back in. Do this every other day. After three weeks of that take it all the way out of the cage then put it back in. After awhile your desert iguana will be used to you handiling it.
