Low or high carbohydrate (CHO) diets (18.9 and 46.3%, LC and HC, respectively) and length of adaptation were investigated in cats ( Felis catus; 10 ± 1 mo, 3 ± 1 kg ) . Cats received each treatment for 14 d in a crossover design and 20 h indirect calorimetry studies were conducted after acute (A; d 0), semi‐chronic (SC; d 4) and chronic (C; d 13) dietary exposure. Data were analyzed by repeated measures ANOVA and Proc Mixed. When cats consumed the HC and LC diet, Ox of the restricted nutrient exceeded intake while Ox of the nutrient in excess matched intake. Mean max energy expenditure (EE) of cats consuming the LC and HC diet were 107 and 102 kcal/kg 0.67 /d and occurred at a mean of 245 and 712 min post feeding, respectfully. Mean max fat (0.90 g/h) and CHO (1.42 g/h) Ox were attained at 26 and 626 min post feeding, respectfully. The changes in Ox and EE suggest that cats adapt to changes in dietary nutrient content, but may require longer than 14 d to adapt to restricted nutrient intake .
