Okay. I'm finally going to post here. I adopted a 12 yr old male. He is a real sweetie and checked out parasite free at the vet. However, for his age, I think he is a little short (fits well into our house then, we're all short!). He is only 3' 6" long. What should he weigh and how do you weigh your iguanas? Also, what foods are suggested for him to help gain weight. I have him on a much better diet and he seems to be filling out a little, but would like to monitor his progress better. Thanks in advance for any help.
