Unquestioning followers can refer to three different animals: SHEEP, lemmings, and CATTLE. SHEEP are a domesticated species of mammal that have been used for centuries as a source of food, clothing, and labor. Lemmings are small rodents that are known for their mass migrations, often leading to their deaths. CATTLE are also a domesticated species of mammal, typically used for their meat, milk, and hides. All three of these animals are known for their tendency to follow the herd without question.
