Key Points

This research aims to understand how different diets affect the gut microbiomes of domestic cats.
Reanalyzed the Kittybiome dataset using 16S rRNA gene amplicon sequencing
Compared microbial composition of cats on dry kibble vs. canned wet food
Significant differences in microbial composition between dry kibble and canned wet food diets
Kibble-fed cats had higher levels of Prevotella, Bifidobacterium, and Megamonas
These bacterial groups are linked to carbohydrate metabolism and metabolic disease.

Abstract

Abstract Domestic cats ( Felis catus ) are understudied regarding how commercial diets impact their gut microbiomes. Here, we reanalyzed the 16S rRNA gene (V4) amplicon sequencing Kittybiome dataset, using new tools and techniques. Results demonstrated significant microbial composition differences between cats eating commercial dry kibble diets and those eating canned wet food. Kibble-fed cats showed enriched Prevotella , Bifidobacterium , and Megamonas amplicon sequencing variants (ASVs), linked to carbohydrate metabolism and metabolic disease.
