Feeding & Dosage Guide

Product Description

Sepili Mouth is a daily dental powder for cats, made to be sprinkled straight onto their food — oral care that's far easier to keep up with than brushing, chews or fiddly routines. Used as part of your cat's daily feed, it helps reduce plaque build-up, freshen bad breath and support a cleaner, healthier mouth over time. If you worry about gingivitis, hefty dental bills at the vet or the stress of a general anaesthetic, Sepili Mouth is a simple, low-stress way to get ahead of bigger mouth problems before they start.

My biggest worry was getting my cat to actually eat it. She’s unbelievably fussy and has turned her nose up at medication, supplements, dental treats, even a new food bowl, for no obvious reason. So I fully expected this to be another waste of money. I started with a tiny amount stirred into her wet food just to test it, and she polished off the lot without so much as a pause. That alone stunned me. I built up to the full scoop bit by bit, and she never seemed to notice it was 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 consistently for her teeth, and this is the first thing that’s actually felt easy to keep up.

I was very sceptical at first because, honestly, it sounded too simple. A scoop of powder in 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 thought I’d give it a month before making up my mind. What surprised me most was the change in breath. That was the first thing I noticed, and it happened quicker than I expected. Then over the next few weeks I could see that the darker build-up near the gum line wasn’t getting worse the way it had been before. I’m not saying it replaces everything a vet does, but for day-to-day upkeep this has been far more useful 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 nearly scrolled past this because my cat is only four, eats normally and still seems completely fine. I honestly thought dental disease was something that happened to much older cats, not one who still tears round the house like a kitten. What changed my mind was reading that cats can have serious build-up and sore gums long before they ever show 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 before. I started mixing the powder into his wet food every morning, and within a few weeks his breath had lost that sour smell I'd got used to. The build-up on the back teeth looks lighter now too. My one regret is assuming "he seems fine" meant nothing was going on.

How Does Sepili Mouth Work?

One scoop 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

    Better 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 comes in 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 cling on, 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 cling on, build up and harden.
  • Cleaner teeth. Fresher breath. Healthier-looking gums.

Plaque builds up over time. Beating it takes consistency. Daily use is what counts.

9 Active Ingredients. Every One Has A Job.

Clinoptilolite (Zeolite)

Breaks up the sticky biofilm that plaque needs to form, so build-up finds it far harder to cling to your teeth.

Probiotic Blend – 6 Strains

Friendly bacteria that fight back against the plaque-causing kind — and stop the bad lot taking over.

Cranberry Powder

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

Dandelion Root

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

FOS / Prebiotic Fibre

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

Yucca Schidigera

Slows the enzymes that weaken gum tissue. Keeps the foundation around your teeth solid.

Zinc Ascorbate

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

Vitamin C

A 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 in. Thousands of cat owners — including those with the fussiest eaters — say their cat tucks in without a second thought.

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 overnight. But it's real, and it builds every single day.

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

Sepili Mouth is designed 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 over their food once a day. That's it. Stir it into wet food for best results. They eat. It works. Job 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 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 tolerate 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.
