It is a multi-strain probiotic with a prebiotic, in capsules that open onto food.

Not for: Owners who want a single-strain, flavoured powder.

What the AI looks for in Cat Probiotic Supplements

Named strains
The label lists genus, species and strain, such as Enterococcus faecium SF68. Probiotic effects are strain-specific, and unnamed blends cannot be judged.
Guaranteed count
CFU guaranteed through the expiration date, not only at the time of manufacture. Live cultures die off during storage.
Cat-specific
Formulated and dosed for cats. Human probiotics may contain additives or strains with no evidence in cats.
Palatability
Choose a flavoured powder or a sprinkle capsule. Daily use only works if the cat eats it.

Brands that matter

  • Purina Pro Plan Veterinary Supplements: FortiFlora is the vet-standard cat probiotic.
  • Nutramax: Proviable is a common multi-strain alternative.

What to avoid

  • Human probiotic capsules
  • Products with no strain names or only 'CFU at manufacture'
  • Storing sachets in a hot place

Questions

Can I give a probiotic during antibiotics?

Vets commonly do. Spacing the probiotic a few hours apart from the antibiotic dose is the usual advice.
