A probiotic helps it recover. Our vet-recommended cat health products range includes palatable options from Purina Pro Plan, Protexin and PAW. They come as sachets, pastes and powders that even fussy cats love.

What do cat probiotics do?
Cat probiotics are supplements that top up the beneficial bacteria in your cat's gut. Those bacteria help break down food, absorb nutrients and support the immune system. Everyday upsets can tip it out of balance: a bout of diarrhoea, a diet change, a stressful move or a course of antibiotics. A good probiotic helps the gut settle and recover. Because cats hide discomfort so well, many cat parents use one both to steady an acute upset and to support daily digestion.
“Probiotic supplements can help restore and maintain a healthy balance of beneficial bacteria in the digestive tract.”
— Dr Jane Miller, BVSc, Veterinarian & Vets Love Pets Partner

When might your cat need a probiotic?
Cat probiotics are most useful when something upsets your cat's gut. Here's when they help most:
- After an upset tummy: a probiotic helps firm up loose stools after a bout of cat diarrhoea.
- After antibiotics: a course can strip out good bacteria, and a probiotic helps replenish them.
- During stress or change: travel, boarding, a house move or a new pet can all unsettle a cat's digestion.
- With a sensitive stomach: cats prone to sensitive stomachs or frequent hairballs often do well on ongoing support.
- In senior cats: gut microbiome diversity naturally declines with age, so many older cats benefit from daily support alongside a moisture-rich senior cat wet food.
A probiotic supports the gut but does not replace veterinary care. If the signs are severe or last more than a day or two, see your vet.
Which cat probiotic is easiest to give?
Cat probiotics come in several forms, and for a fussy cat the form matters as much as the formula. Match the form to how your cat prefers to take it:
- Sachets: Purina Pro Plan FortiFlora is a palatable powder you sprinkle over food. It is made to taste like a treat, which makes it a good first try for a fussy cat.
- Pastes: Protexin Pro-Kolin is a syringe paste you give directly or smear on a paw. It is a common first choice for a sudden bout of diarrhoea.
- Soluble powders: ProN8ure and PAW DigestiCare stir into food or water for easy daily maintenance.
- Capsules: Protexin Synbiotic D-C and Vetafarm Synbiotic suit cats who will take a capsule, or you can open it onto food.
Whichever form you choose, give it daily and follow the label dose for your cat's weight. Most cats take it best stirred through a little wet cat food.
Probiotics or synbiotics: what's the difference?
A probiotic delivers live beneficial bacteria; a synbiotic adds the prebiotic fibre that feeds them. The prebiotic gives the good bacteria a food source, which can help them establish in the gut. Ranges like Protexin Synbiotic D-C and the Pro-Kolin line pair both, while a plain probiotic tops up bacteria alone. If you are unsure which suits your cat, browse the full cat supplements range or ask your vet.

Frequently Asked Questions
Cat probiotics often show results within one to three days for an acute upset, with firmer stools and a steadier appetite. For ongoing digestive support, allow one to two weeks of daily use to see a consistent difference. If diarrhoea has not improved after a couple of days, check with your vet.
Most cat probiotics are given once daily, though the exact amount depends on the product and your cat's weight, so follow the label. During an acute upset your vet may suggest a short, more frequent course. For sensitive or senior cats, a daily maintenance dose is common.
It is best not to give cats human probiotics, because they use bacterial strains and doses chosen for people rather than cats. Feline-specific probiotics like Purina Pro Plan FortiFlora or Pro-Kolin are formulated for a cat's digestive system and palate. Check with your vet before using any human supplement.
Yes, kittens can have probiotics. They are often used to settle the loose stools common after weaning, worming or a change of home. Choose a product labelled as suitable for kittens and use the weight-appropriate dose. See your vet if a young kitten has ongoing diarrhoea, as kittens dehydrate quickly.
Cat probiotics can be given alongside antibiotics to help support the gut. Space them a couple of hours apart so the antibiotic does not kill the live bacteria. Many vets suggest continuing the probiotic for a week or two after the course finishes. Your vet can confirm the best timing for your cat.
