Porcupines are by nature nocturnal creatures. That does not mean that you cannot spot a porcupine in the daytime. Sometimes the African Porcupine can be seen in daytime. Porcupines walking around in daytime usually have some business to attend to, be it migration or mating. Porcupines mate in autumn time. The porcupine will stand on it hind legs and make whining, moaning or grunting noises. A male porcupine will drench his desired female in his urine. If the female takes to the male, she will stand on her hind legs and allow the male to embrace her. She leads the way by raising her tail and disarming her quills, allowing the male safe excess. North American porcupines breed only once every year.
Pregnant female porcupines carry their babies in the womb for 7 months. Baby porcupines are born fully equipped with a full set quills and eyes open. One female usually bares one baby porcupine. Baby porcupines can chew their own within a week but are also fed milk too. They hang around their mothers for about 4 to 5 months before moving on themselves. Porcupines are usually solitary creatures. Sometimes they come together for a feast in summer and in winter where they hang out in dens among rocks.
