One thing I've learned over the years about keeping reptiles is: they don't always behave the same as their wild counterparts and we can never fully duplicate their natural habitat. We can try to keep them as comfortable as we can, but we cannot 100% duplicate their natural habitat. As a result they develop some behavioral problems. A lot of iguanas like eating weird things because no captive environment is ever big enough for them like in the jungle. I don't know. Maybe I'm rambling... [chuckle]
