Primarily solitary creatures, porcupines aren’t known for their cuddling skills. Stalky and slow-moving (not that we’re judging), these walking pin cushions have excellent grip, allowing them to climb up trees where they can stay in the same tree for days. While they may be elusive, porcupines can be spotted at night, near roadsides or huddled up in the trees where it feeds and rests.
