Hello Everyone! I am a new iguana owner and I have some questions. My iguana has some missing scales. I am not sure if she (as we call them Saphira even though we don't know the sex yet) rubbed them off, fell off, or something else. She is about 16-18 weeks old and is about 22 inches long. We have had her for about 6 weeks. We bought her for my niece who turned 16 as a birthday present after thoroughly researching iguana needs, requirements, life expectancy, and size. She has shed once and her head began "graying" a little bit 2 days ago, which was how she shed the first time. Her head and some other areas are graying. I noticed the patches of missing scales this afternoon. Her air temperature in the cage is average 85 - 90, with basking area being around 100, which she does not like to use. Generally she hides in the foliage or under her coconut shells. She eats a variety of leafy greens and squashes and eats fruits like mango. She prefers to eat "after" hours when her day lamp turns off, though we feed her at least twice. She has a shallow water dish that she likes to swim in, especially at night. I can sometimes hold her and sometimes she has an attitude and does not want to be held or touched. I do have 3 dogs who are not around her or her cage, which is currently a 40 gallon tank. We are currently in process of researching and building a larger habitat for when she is larger in size. Any information is helpful. I am also attaching pictures of her and her habitat.
