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.
Mephitis mephitis, the striped skunk species, is the most social skunk and the one most commonly domesticated. When a skunk is kept as a pet, its scent glands are often surgically removed. Skunks can legally be kept as pets in the UK, but the Animal Welfare Act 2006 has made it illegal to remove their scent glands.
