Table 2.

Bodyweight (kg), lean mass (kg), fat mass (kg), and insulin sensitivity index* in cats (Felis catus) fed either kibbled (n = 9) or canned (n = 8) diets at 62 and 260 weeks of age.

Results are reported as mean and associated standard error of the mean (SEM).

^*For the glucose and insulin parameters two data points are missing for the canned treatment group at 62 weeks; additionally for the 260 week data one data point is missing for each the canned and kibbled diet.

^†Insulin sensitivity index = [Glucose]_T0-[Glucose]_T15/[Glucose]_T0.

SEM, standard error of the mean.
