So zilla has had a nice round belly for about a month now and looked like a perfectly healthy igg. Well when I came home from school Monday I noticed her belly was very thin and sunk in and her ribs visible. She is fed the foods on the green iguana society food chart and fed twice a day and she gets lots of food, she gets baths every day and has a mega ray for uvb. She is grounded to the bottom of her cage still as she is a rescue I got 3 months ago that has MBD but its healing. What could have caused this to happen. I'm trying to get my parents to make her an appointment with her vet.
