Herbivore

From UroWiki

A herbivore is an animal that has adapted to eat plants. While some argue that uromastyx are in fact omnivores (creatures including humans which have adapted to eat any available food source, be it plant or animal), and this is certainly true as they have been observed to eat insects, your lizard should nonetheless be treated as a strict herbivore and fed on a greens-and-seeds diet, as the feeding of insects has been observed to cause intestinal and other internal problems with uromastyx.
