Zoologists, such as Adam Britton, believe that such a diet containing protein is unhealthy for the animal's digestive system resulting in severe long-term health damage and death. On the other side of the argument is that Green iguanas at the Miami Seaquarium in Key Biscayne, Florida, have been observed eating dead fish and individuals kept in captivity have been known to eat mice without any ill effects.
Some zoologists, like Adam Britton, contend that a diet consisting mainly of protein can cause irreparable damage to an animal's digestive system, ultimately resulting in severe health problems and death. In contrast, supporters cite the example of Green iguanas at the Miami Seaquarium, which have been seen eating dead fish without showing any adverse effects.
