Vivaldis Vi-fi Forte Spot On for Cats and Kittens from 8 weeks onwards

Vivaldis Vifi Forte Spot-On for Cats -- Monthly Flea & Tick Protection That Actually Works

Your cat is family. And family deserves to live without the misery of fleas burrowing through their fur, ticks latching onto their skin, or the relentless scratching that comes with a chewing lice infestation. The Vivaldis Vifi Forte Spot-On for Cats is a vet-recommended, once-a-month topical treatment that handles all three -- quietly, effectively, and without any drama on your end. One small pipette, applied in under a minute, delivers 30 full days of protection.

This is a pharmaceutical-grade flea and tick Spot-On for cats, manufactured by Disinfecto Chemical Industries Pvt. Ltd. and marketed by Vivaldis Health & Foods Pvt. Ltd. -- a name Indian vets have trusted for years. It is safe for kittens from 8 weeks of age and weighing at least 0.68 kg.

Each 0.5 ml pipette contains: Fipronil -- 9.8% w/v and (S)-Methoprene -- 8.8% w/v.

What Are Its Uses and Benefits?

• The Vifi Forte works as a complete monthly flea and tick treatment for cats, doing far more than just killing what's already on your cat right now.
• It kills adult fleas, ticks, and chewing lice on contact -- giving your cat immediate relief from the parasites making their life uncomfortable. Alongside this, it targets flea eggs and larvae too, breaking the flea life cycle before the next generation can hatch and cause a fresh infestation. This is especially important for Indian households during warm, humid months when flea populations can multiply fast.
• If your cat has been scratching obsessively, developing patchy or irritated skin, or seems unusually restless, Flea Allergy Dermatitis (FAD) could be behind it. This is a skin reaction triggered by flea saliva, and the Vifi Forte helps control and treat it by eliminating the fleas causing it. You can read more about how fleas and ticks affect cats -- and what to do about it -- in this helpful guide on cat fleas and ticks treatment and prevention.
• The treatment is waterproof and remains effective for up to 30 days, even after baths -- so rain, grooming, or a reluctant bath won't undo a month of protection.

What Are Its Side Effects?

• When used correctly and as directed by a vet, the Vivaldis Vifi Forte is generally very well-tolerated by cats. That said, being the attentive pet parent you are, here's what to keep an eye on:
• The application site may look slightly wet or oily for up to 24 hours after you apply it -- this is completely normal. Some cats may experience mild, temporary skin irritation or light redness right at the spot where you applied it; this usually settles on its own within a day or two. If your cat manages to lick the product (which is why you apply it at the back of the neck where they can't reach), they may drool briefly or show signs of oral discomfort -- it looks alarming but isn't dangerous. In rare cases, a cat may show signs of an allergic reaction such as facial swelling, unusual breathing, or extreme lethargy. If this happens, contact your vet right away.
• The vast majority of cats tolerate this treatment with no issues at all. But knowing what normal looks like -- and what doesn't -- is part of being a thoughtful pet parent.

How to Use The Product?

Applying the Vifi Forte Spot-On takes under a minute once you've done it once. Here's how to do it right:

• Hold the pipette upright and snap off the cap. Gently part your cat's fur at the base of their neck, between the shoulder blades -- this is the one spot they cannot reach to lick. Place the tip of the pipette directly on the skin (not the fur on top) and squeeze out the entire contents in one go. Done.
• Let the area dry naturally -- no towel, no hairdryer. Try to avoid petting the treated spot until it's fully dry, which takes about two hours. Do not bathe your cat or let them get wet for at least 48 hours before or after application, so the treatment has time to properly absorb. Repeat every 30 days for continuous protection.

How Does It Work?

You don't need a veterinary degree to understand this -- here's the plain-language version.

• The Vifi Forte contains two active ingredients that work together: Fipronil and (S)-Methoprene.
• Once you apply the solution to your cat's skin, it doesn't enter the bloodstream in any meaningful amount. Instead, it gets stored in the natural oils of the skin and hair follicles, and slowly releases from there across the entire body over the next 30 days. Think of it as the skin becoming a slow-release reservoir -- the active ingredients keep spreading and protecting even weeks after a single application.
• Fipronil is the parasite-killer. It targets the nervous system of fleas, ticks, and lice -- specifically blocking signals that their nerves rely on to function. Without working nerve signals, the parasites die on contact. It handles the adults: every flea, tick, and chewing louse currently living on your cat.
• (S)-Methoprene handles the future threat. It's an Insect Growth Regulator -- it mimics a natural hormone that controls how flea eggs and larvae develop. By interfering with that process, it stops them from ever maturing into adults. This is what breaks the cycle of reinfestation that so many pet parents struggle with.
• Together, these two ingredients cover both the present infestation and the next generation. That's why a single monthly application is all it takes.

Safety Advice

A few important things every pet parent should know before using this product:

• This treatment is for cats only. Never use a spot-on formulated for dogs on a cat -- the ingredients and concentrations are different, and dog formulations can be genuinely harmful to cats. Always check the label.
• Do not use on kittens under 8 weeks of age or weighing less than 0.68 kg. Do not use on cats who are sick, recovering from illness, or significantly underweight without first speaking to your vet. If your cat has ever had a reaction to fipronil or any similar ingredient in the past, do not use this product -- consult your vet for an alternative.
• Keep children away from the application site until it has fully dried. Wash your hands thoroughly after applying. Store the pipette away from direct sunlight and out of reach of children and other pets.
• If you have a pregnant or nursing cat, consult your vet before using this treatment. While fipronil is considered safe in pregnant animals when used at the recommended dose, it is always best to have your vet sign off before introducing any medication during this period.
• In the unlikely event of accidental ingestion by your cat (from excessive licking), contact your vet. Do not induce vomiting without veterinary guidance.

What To Do If You Miss A Dose?

Since this is a monthly treatment, the best practice is to apply it on the same date every month so it becomes part of your routine -- like a recurring calendar reminder.

If you miss an application, apply the treatment as soon as you remember. Then reset your schedule from that new date. Do not apply two pipettes at once to make up for a missed month -- one pipette per application cycle is the correct dose regardless of how much time has passed. If your cat has been exposed to fleas or ticks during the gap, monitor them closely for signs of infestation and speak to your vet if you notice any symptoms.

What Are The Substitutes For This Product?

Do check with your vet before switching, as different products contain different active ingredients and work in slightly different ways.

Quick Tips

A few things that make all the difference when using a flea and tick Spot-On for cats:

• Apply on a calm day when your cat is relaxed -- ideally after they've eaten and are in a sleepy, cooperative mood. A stressed cat makes the application harder than it needs to be.
• If you have multiple cats at home, keep them separated for at least two hours after application so they don't groom each other's treated spots.
• Don't shampoo your cat within 48 hours before or after applying the treatment. Shampooing strips the natural skin oils the product needs to spread effectively.
• Treat your home environment too -- fleas spend most of their life cycle off your pet, in bedding, carpets, and furniture. Washing your cat's bedding and vacuuming regularly during a flea outbreak makes a real difference. For more on this, the Spot-On for cats treatments guide on Supertails is worth a read.
• If you notice fleas still jumping around after treatment, don't panic -- fleas emerging from pupae in the environment can take 2--3 weeks to fully clear. Stick with the monthly treatment and the numbers will drop.
• Mark your calendar or set a phone reminder for your next application date the moment you finish this one. Consistency is everything with monthly flea prevention.

FAQs

Is Vivaldis Vifi Forte Spot-On safe for kittens?

Yes, the Vivaldis Vifi Forte is safe for kittens from 8 weeks of age, provided they weigh at least 0.68 kg. For very young or very small kittens under these thresholds, consult your vet before using any spot-on treatment. Never apply a product labelled for adult cats to a very young kitten without veterinary guidance.

How often should I apply the Vifi Forte Spot-On?

Apply once every 30 days for continuous, uninterrupted protection. Consistency is key -- applying on the same date each month makes it easier to maintain the schedule. Setting a phone reminder the moment you finish each application is a simple habit that keeps your cat protected without any gaps.

Can I use this Spot-On if my cat is pregnant or nursing?

While fipronil is generally considered safe for pregnant animals when used at the correct dose, it is always best to consult your vet before using any medication on a pregnant or nursing cat. Your vet can confirm whether this is the right choice for your cat's specific situation and stage of pregnancy.

What should I do if my cat licks the spot-on after application?

Apply the treatment at the base of the neck between the shoulder blades -- the one spot cats cannot reach. If licking does occur (for example, if a second cat grooms the treated one), your cat may drool briefly or seem uncomfortable. This typically passes on its own. If symptoms persist or seem severe, call your vet.

How long does the Vifi Forte take to start working?

The active ingredients begin working within hours of application and spread across your cat's skin and coat over the next 24 hours. Most pet parents notice a visible reduction in scratching and flea activity within the first 24--48 hours. For heavier infestations, it may take a few days for all adult fleas to die off.

Is Vivaldis Vifi Forte waterproof?

Yes. Once fully absorbed -- which takes about 48 hours -- the treatment is waterproof and remains effective even after bathing. However, avoid bathing your cat or getting them wet within 48 hours of application in either direction, as this can interfere with absorption and reduce how well the product works.

Can I use this Spot-On along with other medicines my cat is on?

If your cat is on any other medications, always check with your vet before adding a new treatment to the mix. While the Vifi Forte is generally safe, drug interactions are always possible and your vet is best placed to advise on what combinations are safe for your specific cat.

Where exactly on my cat's body should I apply the Spot-On?

Apply it directly to the skin at the base of the neck, between the shoulder blades. Parting the fur to expose the skin before applying is important -- the product needs direct skin contact, not just fur contact. This location also ensures your cat cannot twist around to lick it off.
