Veterinary Examination ---------------------- A thorough initial examination is the cornerstone of a health care program for the pet iguana. All newly acquired iguanas, regardless of age, should be thoroughly examined by a veterinarian as soon as possible. Besides a complete physical examination, a blood work-up and stool examination should be included. The advantage of this thorough initial work-up is that current and potential medical problems can be identified and treated before they become serious.
