Abstract

Reptiles often survive on an inappropriate or inadequate diet, but many of the medical problems seen in pet reptiles are largely caused by poor nutrition. This chapter covers special features of reptile nutrition, assessment of growth and body condition, water provision, reptile trophic groups, herbivore, omnivore and carnivore diets, and dietary supplementation.

Respiratory distress in this juvenile Hermann’s tortoise was caused by severe constipation and gas production. In this case, failure to provide a suitable source of water appears to have led to the formation of a bladder stone and subsequent intestinal blockage.
