I had my iguana for about 2 months I made sure he had food and clean water daily. Since he was still getting used to me he wouldn't eat in front of me. I went to my local pet store bought him a basking light a UVB light and a heat lamp and of course his calcium powder. I sprinkled some on the food as instructed by the pet store however my Thomas wouldn't touch his food if the calcium powder was on it. So I stopped putting it on his food and started putting it on him. I cleaned out his tank every 2 days. Long story short I fed him last night a mixture of romaine lettuce and a mixture of vegetables and made sure he had clean water then went to bed. This morning I woke up around 9:30 am and saw Thomas was still sleeping. It gets relatively hot in my home so I turned off his lights for a bit and let him be. I made a bit of noise so he opened his eyes to look at me then went back to bed. It was about 1pm that I realized he was still sleeping so I went to check on him but he wasn't waking up. I tapped on the glass even tried spraying him but nothing. Then I realized he had not been sleeping at that in fact he had passed away. Can anyone please help me understand what I did wrong? I loved Thomas with all my heart he meant the world to me and even in death he STILL means the world to me.
