Abstract

In this study, we present the first comprehensive scientometric analysis of research on the domestic cat microbiome, providing a transparent and data-driven overview of the field. We examined 282 publications on the microbiome of domestic cats (Felis catus) to uncover dominant research themes, methodological patterns, microbial niches, and knowledge gaps. Our results reveal a sharp rise in publications since 2012, with a peak in 2024, where most work is concentrated in high-income countries and driven by a small number of academic institutions. Current efforts are heavily focused on the bacterial gut microbiome, typically using genomic tools for taxonomic profiling in comparative designs. In contrast, research on other microbial communities (e.g., oral or skin), non-bacterial taxa, functional analyses, and behavioural outcomes remains scarce, with behavioural studies virtually absent. Although some studies report health-related effects, mainly positive or neutral, the functional roles of the microbiota and their possible influence on feline behaviour remain largely unexplored. By mapping these trends and gaps, our study provides a strategic framework for advancing microbiome research in domestic cats. These findings highlight priority areas and methodological opportunities that can guide future investigations, foster interdisciplinary collaboration, and ultimately deepen our understanding of the intricate links between microbial ecology, feline health, and behaviour. In particular, studies connecting the microbiome with feline diseases, behaviour, and diet are strongly encouraged, given their high applicability to everyday animal care and management. Such research has the potential to improve both feline health and welfare, while also strengthening the human–cat bond.
