The following photos were taken several weeks ago, just at sunset (which unfortunately these days is way too early).
Generally, a porcupine's eyes are almost invisible. Porcupines are usually too high up in trees or because of their nocturnal habits, under a cloak of darkness. However, with the aid of photography, there's no denying those beautiful brown eyes, which appear to look into your soul.
To paraphrase Nietzsche's quote, "If you gaze long enough into a porcupine, the porcupine will gaze back into you". :)
