1. Here is a definition of a nutrient: a food or chemical that an organism needs to live and
grow, or a substance used in an organism's metabolism which must be taken in from its
environment.
o What is an essential nutrient? Give an example of an essential nutrient?
Essential nutrients are those required by the animal that either cannot be
synthesized by the body or cannot be synthesized in adequate amounts for good
health. They are supplied by complete, balanced nutrition (WALTHAM Essential
Nutrition for Cats and Dogs, 6). An example of an essential nutrient is water.

for Cats and Dogs. 2009.
o What are non-essential nutrients? Give an example of a non-essential nutrient?
Non-essential nutrients are nutrients that can be made by the body or can be
absorbed through certain foods. Though they are called non-essential, they are
still vital to maintaining the health of the animal. An example of non-essential
nutrients are minerals. They can be naturally present within the ingredients used
to make pet food (WALTHAM Essential Nutrition for Cats and Dogs, 44).

o What is the most essential nutrient for cats and dogs?
The most essential nutrient for cats and dogs is water. It makes up 75% of their body at
birth and 60% in adult life. Water is an ideal medium for transporting nutrients and waste
through the body, it’s required for most metabolic processes, it regulates body
temperature, and lubricates the joints, eyes, and inner ear (WALTHAM Essential
Nutrition for Cats and Dogs, 13)

2. Nutrient Requirements:
o Who determines nutrient requirements of cats and dogs? (From the essential cat
and dog nutrient article)
There are various different bodies that produce the guidelines for the nutrient
requirements for dogs and cats. These bodies base this off of a lot of scientific research
that has been done, and all are somewhat similar in their guidelines, but differ slightly
because of differences in interpretation of scientific evidence (WALTHAM Essential
Nutrition for Cats and Dogs, 7). These bodies include the National Research
Council, the American Association of Feed Control Officials, the Fédération
Européenne de L’Industrie des Aliments Pour Animaux Familiers, and
WALTHAM.
