Hi my red iguana has not been eating or drinking for a few days now. he's about 2 and a half years old and I'm extremely worried about him. He has been sneezing a lot more than normal and also not very active. Normally he will run from me at first but now he's not. He's been sleeping a lot too. I have zoo med basking lamp and a EXO Terra uvb bulb. He has a large bowl of water that he can soak in and a hammock that he sleeps on. I feed him collard greens dandelion leafs and mustard greens and on occasion kale.i dust his food with calcium powder. His basking spot is about 85 I have to get a new heat gun as I don't like thermometers so I don't know the exact temperature right now. I have a vet appointment for Tuesday march 7th 2017 but I'd like to know if you guys possibly know what's wrong with him. He's everything to me and I don't wanna lose him. He's currently in a 55 gallon tank until I get his enclosure built.
