I have an iguana that keeps eating and eating all day long!

I remember a cat that ate and ate fish until he puke and after that he continued eating.

I'm giving my iguana(Chole) several vegetables, fruits, flowers and juvenile food but she doestn't stop. Is it safe for her?

BTW, she walks freely inside my house looking for sunlight during the day but is trained to use her sandbox(Below and outside her terrrarium) when she needs it, so she exercise a lot.
