The feline gut microbiome influences health and behaviour. Understanding its connections to diet, stress, and welfare is an emerging area of companion animal science.
The feline gut microbiome is increasingly recognised as a key mediator of health and wellbeing. A diverse, balanced microbiome supports immune function, mental health through the gut-brain axis, and resistance to disease. Diet quality is the primary modifiable determinant of microbiome composition in cats. High-quality, species-appropriate diets with consistent protein sources support microbiome stability. Chronic stress disrupts the microbiome, potentially contributing to the gastrointestinal symptoms seen in stressed cats. Research into feline probiotics and prebiotics is promising but early — consulting a veterinary nutritionist is advisable before supplementation for cats with gastrointestinal problems. Gut health monitoring is increasingly part of comprehensive feline wellness assessment.
