Inulin and faecal microbiota and immune markers in cats
Faecal secretory IgA increased at day 14 and Collinsella abundance increased. Indole and 3-methylindole did not change.
Review scope
Abstract-based review. Full methods, complete statistical results and product equivalence have not been appraised. This is research context, not an individual feeding or treatment recommendation.
Study question and design
Eight healthy adult British Shorthair cats. Inulin at 50 mg/kg body weight daily for 21 days, with repeated faecal sampling.
Main findings
Faecal secretory IgA increased at day 14 and Collinsella abundance increased. Indole and 3-methylindole did not change.
Limitations and applicability
No parallel control was described in the abstract. Biomarkers do not demonstrate improved clinical health or immune protection.
Ingredients investigated
Direct ingredient investigations
Inulin
Direct · cat. Eight healthy adult British Shorthair cats.
Tested form: Supplemental inulin; exact source and preparation not established in the reviewed abstract. Dose: 50 mg/kg body weight/day (Daily oral dose per kilogram of body weight). Duration: 21 days. Comparator: Pretreatment baseline; no parallel control group described in the reviewed abstract.
Measured finding: Secretory immunoglobulin A increased on day 14 and Collinsella abundance increased. Indole and 3-methylindole did not change.
Limitations: Eight cats and no parallel control described in the abstract. Biomarker outcomes; source form and commercial-product dose require separate verification.
Evidence.pet interpretation
Apply this result only within its species, preparation and study conditions. An ingredient listing alone does not establish that a commercial product reproduces the tested intervention.
Funding and conflicts
Not established from the reviewed abstract.
Ingredient references
These are research references. The tested form, dose and formulation must be matched before using a result to support a product claim.
