1 Multiple sclerosis (MS) is a disease that causes demyelination (disruption of the myelin that insulates and protects nerve cells) of spinal nerve and brain cells.  Although the exact case is unknown, multiple sclerosis is considered to be an autoimmune disease.
The skunk is not a rodent. They belong to the family Mephitidae and the order Carnivora which does not include rodentia. They are sometimes placed in the family Mustelidae (weasels) but have been discovered to be less related than was thought.
Two skunk species live in Washington: The striped skunk (Mephitis mephitis, Fig. 1) is the size of a domestic cat, ranging in length from 22 to 32 inches, including its tail. Its fur is jet black except for two prominent white stripes running down its back.
