A GOOD APPETITE
for natural food and a relish for simple, healthful articles of diet, are
signs of a normal condition of body and mind. Satisfaction should be reached
before satiation, and should be followed by no unpleasant feeling of fullness
or tightness. Digestion should proceed quietly and unconsciously.
WHEN THIRSTY, there should be desire for fruit, or water only.
THE URINE,
should be clear and of a golden yellow color. It should have neither a sweet, sour, nor pungent odor, nor should
it coagulate when boiled. Its voiding should proceed easily, and without pain.
THE FAECES,
should be of a yellowish brown color, solid and cylindrical, as seen in healthy
animals. They should leave the rectum without soiling it.
