I did some more iguana research today and have concerns. I learned that my iguana is most likely a female and is showing signs that she is gravid. She has increased agitation she has a loss of appetite and is pretty plump. I'm starting to think she may need to lay. I'm not 100 percent sure on what to dk. She is an indoor ig. She is 2 yrs old and about 10 to 11 in stv. I'm think of making a nest box would like some advice on the best way to do it for an indoor enclosure. Any help would be great.
