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.
By 10 months of age, both males and females reach sexual maturity. Many skunks do not survive their first full year, falling victim to severe winter weather conditions, infectious disease, automobiles or predation by birds of prey, bobcats, foxes, mountain lion and coyotes.
