Hi, just wondering if anyone knows if this is just old age or something else. I have an iguana that is approx. 18 years old. I have noticed lately that I can see her bones sticking out on either side of her tail. Since I moved 4 years ago her appetite hss changed. She does not eat as much greens as she used to in fact she doesn't eat much at all compared to what she used to in the other house. She used to eat 3 times a day and now she is down to one. She is getting the proper lighting. Any ideas?
