I think it is all dependent upon care and genetics. Cami hit a year old, and seemed to go down a little in health. She came from PetSmart, and was in a terrible situation with probably some not-so-good genetics. Sol just hit 1, and is doing awesome. He was purchased from a reptile breeder at a show, who had both parents on site with her. Genetics and husbandry are all so important, I am praying Cami lives past 2, and I know Sol will last for a long time!
