  1. LEAN lean cats, OBWL obese cats before weight loss, OAWL obese cats after weight loss
  2. The relative abundances across taxa presented here represent the fecal microbiota of healthy lean cats (LEAN, n = 14) and obese cats (OBWL, n = 17) following a 4-week adaptation period with a veterinary therapeutic food intended for weight loss and adult maintenance, and obese cats after a 10-week weight loss period on the same food (OAWL, n = 16). Cut-off for phyla and genera in the study were 1 and 0.1%, respectively. However, only a portion of the most abundant members for all taxa (besides to phyla) are presented in the table. No significant differences were found between groups, using Wilcoxon Rank Sum and Wilcoxon Signed-Rank, depending on the groups’ comparison, followed by the Benjamini-Hochberg adjustment (P > 0.05 for all comparisons; not shown in the table)
  3. a The numbers after each taxa represent the number of members in the specific taxa presented in the table out of the overall number of members in that taxa retrieved by the analyses
