When we were camping in Forillon National Park (Parc National Forillon) Gaspe, Quebec I came across a porcupine eating leaves. The video is somewhat long, but fascinating, especially about three-quarters of the way through when he/she stands to eat, you then get a good look at its face. You will note that I say to my husband something to the effect of get back it will shoot its quills. Hubby was getting too close, but no porcupines do not shoot quills. However, their quills are difficult to remove when you are pierced with one, they will grow new ones.
