  1. The daily intake of all essential nutrients was calculated from each cat’s food intake and the average nutrient content of the diet (Table 5) and expressed per kg BW ^0.67. Results are written as median (range)
  2. aMinimum daily intake defined as the least daily intake that the cat consumed during the maintenance period
  3. bMaximum daily intake defined as the greatest daily intake that the cat consumed during the maintenance period
  4. cAverage daily intake was defined as the mean daily intake for the whole maintenance period
  5. d Minimum requirement: the minimal concentration of a maximally bioavailable nutrient that will support a defined physiological state [4]
  6. e Adequate intake: the concentration of nutrient demonstrated to support a defined physiological state when no minimal requirement has been demonstrated [4]
  7. f Recommended allowance: the concentration of nutrient demonstrated to support a defined physiological stage [4]
  8. g All requirements are expressed as the unite stated per kg BW^0.67
