Companion Animal Welfare

Companion Cat Microbiome and Diet Welfare

The feline gut microbiome plays a critical role in immune function and welfare, with diet being the primary modifiable determinant of microbiome health.

Key Facts

Cats are obligate carnivores with a gut microbiome adapted to high-protein low-carbohydrate diets
Dysbiosis of the feline gut microbiome is associated with IBD, obesity and immune dysfunction
High quality protein sources support beneficial microbiome species diversity
Ultra-processed pet foods may negatively affect microbiome composition in some cats
Prebiotic fibre in appropriate quantities supports beneficial bacterial populations

Welfare Considerations

Feline gut microbiome science is advancing understanding of diet-welfare relationships. Evidence suggests that high-quality, appropriate diets support microbiome diversity associated with better immune and gut health. Feed quality decisions are long-term welfare investments rather than optional premium choices.

What You Can Do

Choose cat foods with named high-quality protein as the primary ingredient
Discuss diet transitions with your vet if your cat has chronic gut or immune issues
Support research into feline microbiome health and its welfare implications
