Reindeer are herbivores and do not typically eat meat. They primarily consume plants, like lichens, grass, and other vegetation. They have a unique digestive system that allows them to digest this tough, fibrous food. Reindeer will sometimes eat small animals, like rodents, if they're unable to find enough plant-based food. Reindeer are not known to eat arctic foxes, as these animals are too small and fast-moving for the reindeer to catch. Reindeer may also see arctic foxes as potential predators, so they're more likely to avoid them than to try to eat them
