Answer:

There are animal, pet owner, and product factors to consider when selecting a diet:

• Animal factors:
  1. Species—cats have more stringent nutrient requirements than dogs.
  2. Life stage—puppies and kittens have more stringent nutrient requirements than adults.
  3. Spay/neuter status—intact animals typically require more calories and may need a more energy dense diet.
  4. Activity level—a sedentary animal may need a less energy dense diet.
  5. Health status—certain disease conditions may warrant special dietary intervention.
• Client factors:
  1. Cost—can the owner afford the diet?
  2. Convenience—is the food readily available?
  3. Personal preference—does the owner prefer to feed only dry food?
  4. Personal values/beliefs—is the owner looking specifically for a natural diet or a vegetarian diet due to personal lifestyle?
• Product (diet) factors:
  1. Is the diet complete (contains all required nutrients^1,2) and balanced (all nutrients in proportions^1,2) for the species and life stage?
  2. Is the diet palatable? Will it be eaten willingly and in sufficient amounts to keep the pet in ideal body condition?^1,2
  3. Is the diet formulated so nutrients can be absorbed and utilized by the body?^1,2
  4. Is the diet free of toxins, contaminants, and unsafe ingredients?^1,2
