All pet owners want their pets to be in good health. We want nice shiny coats on our dogs and cats. We want crystal clear water for our fish and marine animals, and we want nice clean cages for our birds and reptiles. We can always tell when our pets are not feeling so hot. They crawl up in a ball and lie in the corner. They hide behind a rack in their fish tank and have white little dots on them, and their stool looks anything but normal.
