Serum chemistry results determined in cats at pre-neutering, 7 days post-neutering, 13-days post-neutering, and 6 months post-neutering.^*

<p>*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<0.05.</p

Body composition measurements determined in cats at pre-neutering, 13 days post-neutering, and 6 months post-neutering.^*

<p>* 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<0.05.</p>†<p>BW (D₂O)  =  Body weight at time of deuterium oxide (D₂O) measurements. LBM  =  Lean body mass. FM  =  Fat mass. BW  =  Body weight.</p

Mean (± SEM) weekly body weight (BW) in the male cats following neutering.

<p>Week 0 is designated as baseline (immediately before neutering). Cats were fed at pre-neutering maintenance food intake from week 0 to week 2. The vertical line denotes the beginning of <i>ad libitum</i> feeding (week 3 to week 28). The asterisk over the bracket covering week 4 to week 28 denotes significant differences in average weekly BW from the averaged values from week 0 to week 2, p<0.05.</p

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

Mean (± SEM) weekly food intake (FI) in the male cats following neutering.

<p>Week 0 is designated as baseline (immediately before neutering). Cats were fed at pre-neutering maintenance FI from week 0 to week 2. The vertical line denotes the beginning of <i>ad libitum</i> feeding (week 3 to week 28). Asterisks over the brackets covering week 3 to week 19, and week 24 to week 27 denote significant differences in average weekly FI from pre-neutering maintenance FI, p<0.05.</p
