Food intake, body weight, and energy expenditure measurements in cats at pre-neutering, 3–4 days post-neutering, and 9-days post neutering.*

* Values are given as mean ± SEM. For rows in which superscripts are present, values in a row that do not share a common superscript differ by p†BW (D2O) included as a covariate.‡LBM included as a covariate.§FI = Food intake. EI = Energy intake. BW = Body weight. RQ = Respiratory quotient. TEE = Total energy expenditure. TEE/BW0.75 = Total energy expenditure/Metabolic body weight. REE = Resting energy expenditure. REE/BW0.75 = Resting energy expenditure/Metabolic body weight. LBM = Lean body mass.
