Feeding & Dosage Guide

Product Description

Sepili Mouth is a daily dental powder for cats made to be sprinkled straight onto their food, so looking after their teeth is far easier to keep up than brushing, chews or messy routines. It works as part of your cat's normal feeding routine to help reduce plaque build-up, freshen bad breath and support a cleaner, healthier mouth over time. If you worry about gingivitis, hefty vet dental bills or the stress of a general anaesthetic, Sepili Mouth is a simple, low-stress way to stay ahead of bigger mouth problems before they start.

My biggest worry was whether my cat would actually eat it. She’s unbelievably fussy and has knocked back tablets, supplements, dental treats, even a new food bowl, for no reason at all. So I was fully expecting another waste of money. I started with a tiny bit stirred through her wet food just to test it, and she polished off the lot without so much as a pause. That alone shocked me. I worked up to the full scoop gradually and she never seemed to notice it was in there. After about a month her breath was noticeably better and the build-up on her teeth didn’t look as dark to me. For anyone with a difficult cat, that was the real win here. I’d pretty much given up on doing anything regularly for her teeth, and this is the first thing that’s actually felt easy to keep up.

I was pretty sceptical at first because, honestly, it sounded too simple. A scoop of powder in her food didn’t seem like it could make any real difference when vets charge hundreds for a dental and make it sound so serious. I wasn’t expecting miracles, but I figured I’d give it a month before making up my mind. What surprised me most was the change in her breath. That was the first thing I noticed, and it happened faster than I expected. Then over the next few weeks I could see the darker build-up near the gumline wasn’t getting worse the way it had been. I’m not saying it replaces everything a vet does, but for day-to-day upkeep it’s been far more helpful than I thought it would be. It made me realise I’d been ignoring the problem mainly because I didn’t think I had a realistic option at home.

I almost scrolled past this because my cat is only four, eats normally and still seems completely fine. I honestly thought dental disease was an old-cat problem, not something to worry about with a cat who still tears around the house like a kitten. What changed my mind was reading that cats can have serious build-up and sore gums long before they show any obvious pain. I had a proper look at his back teeth and spotted a yellowish line along the gumline that I'd never really noticed. I started mixing the powder through his wet food every morning, and within a few weeks that sour smell on his breath — the one I'd just gotten used to — was gone. The build-up on the back teeth looks lighter now too. My biggest regret is assuming “he seems fine” meant nothing was going on.

How Does Sepili Mouth Work?

One serving sprinkled over your cat’s food. Wet or dry. That’s it. From there, Sepili

Mouth works through your cat’s saliva 24/7, coating the mouth, fighting plaque 

build-up and helping keep their teeth and gums healthy.

  • DAY 7

    Fresher Breath

  • Zinc neutralises the sulphur compounds behind bad breath.
  • Prebiotics and probiotics work together to crowd out odour-causing bacteria.
  • First sign: fresher breath when your cat gets up close.
  • DAY 45

    Visible Changes

  • Zeolite has been breaking up the sticky biofilm that plaque needs to form.
  • Cranberry has been making it harder for plaque-causing bacteria to stick, day after day.
  • The result: less build-up and cleaner-looking teeth.
  • DAY 90

    Full Impact

  • All 9 ingredients have had time to work together, day after day.
  • Plaque has had fewer chances to stick, build up and harden.
  • Cleaner teeth. Fresher breath. Healthier-looking gums.

Plaque builds up over time. Beating it takes consistency. Daily use is what makes the difference.

9 Active Ingredients. Every One Pulls Its Weight.

Clinoptilolite (Zeolite)

Breaks up the sticky biofilm that plaque needs to form, so buildup can't get a grip on your teeth.

Probiotic Blend – 6 Strains

Good bacteria that crowd out the plaque-causing kind, so the bad ones never get the run of the place.

Cranberry Powder

Makes it harder for plaque-causing bacteria to cling to teeth. Stops build-up right where it starts.

Dandelion Root

A root packed with natural antioxidants. Extra defence against everyday cellular stress.

FOS / Prebiotic Fibre

Fuel for the good bacteria. Keeps your probiotic blend fed and ready to work.

Yucca Schidigera

Slows the enzymes that break down gum tissue, so the foundation around your teeth stays solid.

Zinc Ascorbate

Plaque bacteria can't stand zinc. It goes after the bacteria and neutralises the sulphur compounds behind bad breath.

Vitamin C

The building block for collagen — what strong, resilient gums are made of.

Taurine 

Works with zinc to keep gum tissue strong. An essential amino acid every cat needs.

Frequently Asked Questions

Will my fussy cat actually eat it?

Most cats don't even notice it's there. Just sprinkle one small scoop over their wet food and stir it through. Thousands of cat owners — including plenty with seriously fussy eaters — say their cat eats it without missing a beat.

How soon will I see a difference?

Most owners notice fresher breath within the first 2 weeks. Visible plaque reduction takes longer — usually 8 to 12 weeks of consistent daily use. It's not an overnight fix. But it's real, and it builds every single day.

My cat already has plaque build-up is it too late?

Sepili Mouth is made for daily upkeep at any age and helps reduce new plaque build-up as part of your cat’s routine. If your cat already has heavy tartar, red or bleeding gums, drooling, or signs of mouth pain, see your vet. Existing dental disease needs professional care, and Sepili Mouth is not a treatment.

How do I give it to my cat?

One small scoop on their food, once a day. That's it. Stir it through wet food for best results. They eat. It works. Done.

What if it doesn't work for my cat?

Try it for 90 days, completely risk free. If you don't see a difference — fresher breath, cleaner teeth, a happier cat — we'll refund you in full. No hoops. No hassle. No questions asked. You've got nothing to lose and a healthier cat to gain.

Is Sepili Mouth safe? Any side effects I should know about?

Sepili Mouth is made for daily use and most cats take to it well. Follow the directions on the label. If your cat has a health condition, is on medication, or is pregnant or nursing, check with your vet first. Stop use and contact your vet if you notice any reaction.
