My new iguana is 4 yrs old. I've had him for a week. He's doing OK attitude wise. But he's not eating. The rescue said they had him for a month. He's very thin. Should have basking shelves up this weekend. Cage is 10x6 but only 5 ft high. Temp @85 during day 75 at night. He sometimes sits under the basking light on the floor. Misted a few times a day with a 30 daily soak/potty time. Any advice helpful. Been a long time since I've had an iguana. PS why are they no longer selling lights with safety grills?
