Hi guys, I am a little worried about my green iguana as his habits seemed to of changed dramatically. When I first got him he came from a place where he was able to run free around the house however he was not handled or tame. At this point he was approximately 6 months old. Before I got him I previously built him a house that stood 5ft high and 3ft square with adequate heating and ultraviolet lighting. He seemed happy in his new home however his aggressive behaviour was still prominent in response to the spitting and whipping. He grew out of this environment very fast so the time came to built him a new home which is approximately 8ft high and 12ft long and 5ft in depth. The heating is good in his basking area which he spends a lot of time in. However when he is not there he is trying to escape out of all the glass panels, the glass panels give him a view to the whole outside area and lets in natural sunlight light too. Within his home he has fresh running water adequate lighting, heating, humidity and furthermore lots of activity things to climb on in order to keep him active. My concerns start here as he has become so aggressive and whips out, spits and now lunge bites. He has become a wild animal that crocodile rolls in your hands ripping them to bits. He is 1 year old now, and seemed to like his new environment at first but since being in there his habits changed dramatically. He has now gone completely of his food and picks at it every so often additionally he has not shed his skin in over 7 weeks. I am aware that iguanas are creatures of habit and do not like change, however there was not an option as he grew very fast and needed moving into an appropriate environment. He adjusted to this well at first but now seems unhappy. I would appreciate any comments to help resolve this current situation and give him a happy and content life, many thanks for your time and expertise. Mike Silver.
