Only a few weeks old and already thousands of quills! On August 4, Zoo Vienna welcomed a baby North American Porcupine. The porcupette is a female and weighed in at just about 1.3 pounds (600 g) at her first medical checkup. The gestation period for porcupines is relatively long, around seven months, so the juveniles are already well-developed at birth. They come into the world with eyes open and can run immediately. At just a few days old, the porcupette had started to practice climbing. Now at one month old, she still drinks milk but also nibbles on carrots, apples, beetroots, and branches. She will be weaned at one and a half months old.
Although North American and European Porcupines might look very similar, they are actually not very closely related. North American Porcupines are the second largest New World rodent, after the North American Beaver. Commonly found from Alaska to Mexico, they are excellent albeit slow climbers and spend most of their lives in trees. These herbivores are crepuscular, meaning that they are mainly active at dawn and dusk. A single North America Porcupine may have up to 30,000 barbed quills for self-defense. At birth, the quills of a porcupette are short and soft, but they harden after a few days.
