Diet & Nutrition

  • Hand-raised babies usually make better pets, as they have been completely socialized with humans. Hand-feeding is a job best left for the experienced bird breeder or aviculturist. If you are considering hand-feeding a baby bird, you should contact your local bird breeder or avian veterinarian for help. This article provides general guidelines and best practices.

  • Guinea pigs can be hardy and easy to care for when provided an appropriate environment for their unique needs. Like all animals, guinea pigs are susceptible to certain problems and diseases. This handout outlines the diagnosis, treatment, and prognosis for some of the more common health problems of guinea pigs.

  • A pet hedgehog’s diet should mainly consist of high-quality hedgehog food mixed with high-quality, low-fat cat food. The diet may be supplemented with certain insects, fruits, and vegetables, which are listed in this handout. Foods that should be avoided are also listed. Hedgehogs have a propensity for obesity if their food intake is not monitored or controlled.

  • This article outlines general guidelines on food intake and supplementation for iguanas. Opinions vary on the nutritional needs of captive iguanas and our knowledge in the subject is continually expanding based on new dietary studies in reptiles. Check with your veterinarian for specific nutritional needs for your pet iguana.

  • Feathers insulate to maintain a bird's body temperature and protect birds from the elements and play an important role in aerodynamics and flying. Feathers need to be removed or fall out to stimulate new feather growth. A bird needs to molt each year to get rid of old or damaged feathers. A pet bird's exposure to varied daily light cycles may lead to an irregular or incomplete molt that may be longer or shorter than a normal molt.

  • Obesity is a major problem in older birds on seed-based diets and can contribute to diseases such as arteriosclerosis, atherosclerosis (fat deposits in major arteries), and fatty liver disease (hepatic lipidosis). Unlike their wild counterparts, pet birds are not given as much opportunity for daily exercise. Pet birds often burn off very few calories in their daily lives. Switching a bird from an all-seed diet to a more suitable diet consisting mainly of pellets, with smaller amounts of fresh vegetables and fruit, will decrease its overall daily intake of calories.

  • Like rabbits and guinea pigs, prairie dogs require a diet high in fiber. As they are hind-gut fermenters, they need alfalfa up to one year of age and Timothy hay after one year of age plus a high quality prairie dog pellet. Treats should be kept to a bare minimum as prairie dogs are prone to obesity.

  • Abdominal swelling in any reptile is always a concern that needs to be brought to the attention of a veterinarian well versed in reptile medicine. In female reptiles, this swelling often means that the individual has eggs or fetus that are ready to be delivered. When the female cannot deliver the eggs or babies, this is referred to as dystocia. This condition can be life threatening and need attention ASAP.

  • Swellings on or around the joints in reptiles can be an indication of uric acid deposits in the area. This condition is referred to as gout. Gout is often painful and may also affect internal organs. Treatment will require medications and sometimes surgery.

  • Sugar gliders are small marsupial mammals that are omnivorous eaters, meaning they eat a wide variety of foodstuffs. Items from insects to eucalyptus to gum from the acacia tree may all be consumed to a varying degree. Improper nutrition is one of the most prominent causes of illnesses in sugar gliders. This handout provides the information needed to feed your sugar glider a healthy diet.
