The rodent family includes more than just rats and mice; it also includes porcupines like Eddie! Prehensile-tailed porcupines are a type of arboreal rodent with sharp quills, long tails, and teeth that never stop growing. As herbivores, they mainly eat fruit, roots, vegetables, and stems, but their front teeth, or incisors, are perfectly designed for cutting through tough plant material like bark, twigs, and leaves! | Brookfield Zoo Chicago
