What Is Kiwof Cat Dewormer?

Kiwof is a broad-spectrum antiparasitic medication designed specifically for cats. It comes as a chewable tablet, making it easier to administer than liquids or injectables. The formula contains two active ingredients — levamisole (5 mg) and oxantel pamoate (10 mg) — that work together to eliminate multiple types of internal worms that commonly infect cats.

This is a prescription medication in most countries, which means your veterinarian must assess your cat before recommending a dose. That safety gate exists because deworming strength depends on your cat's weight, age, and overall health. A vet calculates the right dose to kill parasites without harming your cat.

Kiwof works on three major parasite types: roundworms (Toxocara cati and Toxascaris leonina), hookworms (Ancylostoma tubaeforme and Uncinaria stenocephala), and tapeworms (Dipylidium caninum). If your cat has a different worm species, your vet may recommend a different dewormer  that's why the diagnosis step matters.

How Kiwof Works: The Deworming Process

Kiwof's active ingredients paralyze worms in your cat's digestive tract. Here's what happens after you give the tablet:

Within 1–2 hours: The medication reaches your cat's intestines and bloodstream. Levamisole paralyzes the worm's nervous system, and oxantel pamoate works on the worm's muscles. The worms lose the ability to grip the intestinal wall and move.

Within 24–48 hours: Paralyzed worms detach from the intestinal lining and are expelled through feces. Some cat owners report seeing dead worms in the litter box — this is normal and confirms the medication is working.

After 48 hours: Worm burden drops significantly. Most cats need only one dose for effective treatment, though some infections require a second dose 2–3 weeks later to catch any worms that were in the egg stage during the first treatment.

The reason Kiwof requires a vet prescription is this: dosing is weight-dependent. A 4-pound kitten needs less medication than an 12-pound adult cat. Too little won't kill all worms; too much can cause side effects. Your vet weighs your cat and calculates the exact tablet dose needed.

Why Cats Get Worms (And Why Treatment Matters)

Indoor cats can get worms even if they never go outside. Here's how:

Fleas carry tapeworm eggs. If your cat has fleas, it can ingest flea eggs while grooming and develop tapeworms. This is one reason vets recommend year-round flea prevention.

Contaminated food and water. Raw or undercooked meat, contaminated soil, and stagnant water can harbor roundworm and hookworm eggs.

Mother-to-kitten transmission. Nursing kittens can contract worms from their mother's milk if she's infected.

Hunting. Outdoor cats pick up worms from eating infected prey — mice, birds, insects.

Left untreated, worms steal nutrients from your cat, causing weight loss, dull coat, diarrhea, and lethargy. Severe infections can cause anemia (hookworms) or intestinal blockage (tapeworms). Kiwof stops this cycle quickly, usually within one dose.

Benefits of Kiwof for Cat Owners

Fast acting: Most cats show improvement within 48 hours. Worms are expelled and your cat starts absorbing nutrients properly again.

Chewable format: Unlike liquid dewormers that cats refuse or injectables that require a vet visit, Kiwof tablets can be given at home. Many cats accept them as treats (mix with wet food if needed).

Broad-spectrum coverage: One medication treats three major worm types. You don't need separate treatments for roundworms vs. tapeworms.

Trusted formula: Levamisole and oxantel pamoate have been used in veterinary medicine for decades. Safety profile is well-established when dosed correctly.

Affordable option: Compared to multiple vet visits or specialized antiparasitic drugs, Kiwof is cost-effective, especially when treating multiple cats in a household.

Dosage and How to Give Kiwof to Your Cat

Your veterinarian determines the correct dose based on your cat's weight. Generally, the formula is 1 tablet per 2.2 pounds (1 kg) of body weight, but always follow your vet's specific instructions.

How to administer:

Place the tablet in the back of your cat's mouth (far enough that swallowing is easier than spitting it out). If your cat resists, crush the tablet and mix it with a small amount of wet food — fish-flavored foods often work best.

Some cat owners wrap the tablet in a small piece of wet food to disguise it. This works well if your cat swallows without chewing.

If your cat vomits the tablet back up within 30 minutes, contact your vet — you may need to re-dose.

Timing: Kiwof can be given with or without food, though food may help reduce mild stomach upset.

Follow-up dose: If your vet recommends a second dose, wait 10–14 days before administering it. This catches any worms that were in the egg stage during the first treatment.

Possible Side Effects and What to Expect

Side effects are rare when Kiwof is dosed correctly, but some cats experience mild symptoms as worms are expelled:

Vomiting or diarrhea: The most common side effect. Usually mild and self-limiting (stops within 24 hours). It's often the worms being expelled, not the medication itself causing harm.

Loss of appetite: Some cats eat less for a few hours after dosing. Appetite typically returns within 12–24 hours.

Lethargy: A few cats sleep more than usual on the day of treatment. This is normal as their body processes the medication and expelled parasites.

Visible worms in stool: Frightening to see, but completely normal. Dead worms in the litter box confirm the medication is working.

Rare serious side effects: Tremors, excessive drooling, or difficulty breathing are rare and indicate overdosing. Contact your vet immediately if these occur.

The key safety factor: never exceed the vet-prescribed dose. Over-dosing is what causes serious side effects, not the medication itself at the correct dose.

When to Use Kiwof: Timing and Prevention

Use Kiwof when:

• Your vet diagnoses worms via fecal exam (stool sample under microscope)
• Your cat shows signs: weight loss despite eating, dull coat, diarrhea, visible worms in stool or vomit, or scooting (dragging rear on ground)
• You have multiple cats and one is confirmed infected (treat all to prevent spread)
• Your cat hunts outdoors or has regular flea exposure

Prevention (reducing future infections):

• Monthly flea prevention (fleas carry tapeworm eggs)
• Keep litter boxes clean and separate from feeding areas
• Avoid raw or undercooked meat for your cat
• Indoor-only cats have lower infection risk but aren't immune
• Kittens under 12 weeks old should have a vet-supervised deworming protocol

Most vets recommend a fecal exam every 6–12 months for outdoor cats and annually for indoor cats, even if you don't see symptoms. Caught early, worm infections are easy to treat with Kiwof.

Kiwof vs. Other Cat Dewormers: A Quick Comparison

Dewormer	Active Ingredient	Worm Coverage	Format	Prescription Required
Kiwof	Levamisole + Oxantel	Roundworms, hookworms, tapeworms	Chewable tablet	Yes
Drontal	Pyrantel + Praziquantel	Roundworms, hookworms, tapeworms	Tablet or paste	Yes
Profender	Emodepside + Praziquantel	Roundworms, hookworms, tapeworms	Topical liquid	Yes
Panacur	Fenbendazole	Roundworms, hookworms, some tapeworms	Powder or liquid	No (OTC in some regions)

 

Kiwof and Drontal are comparable in efficacy and coverage. The main difference: Kiwof's chewable format vs. Drontal's tablet or paste. Profender is topical (applied to skin), which some cats prefer. Panacur covers fewer tapeworm species but is available over-the-counter in some places.

Your vet chooses based on your cat's specific parasite type, age, and health status. All are safe when dosed correctly.

Frequently Asked Questions About Kiwof Cat Dewormer

Is Kiwof safe for kittens?

Kiwof is generally safe for kittens over 6–8 weeks old, but your vet determines the exact age and weight threshold. Very young or very small kittens may need a different dewormer or a delayed start until they reach a minimum weight. Always consult your vet before deworming a kitten.

How often should I deworm my cat?

If your cat has worms, one or two doses of Kiwof (2–3 weeks apart) usually resolves the infection. For prevention: indoor cats need a fecal exam annually and deworming only if worms are detected. Outdoor cats should be dewormed 2–4 times per year or whenever a fecal exam shows infection. Kittens have a different schedule — ask your vet for a kitten deworming protocol.

Can I give Kiwof to a pregnant or nursing cat?

Not without vet approval. Pregnancy and nursing can affect how a cat's body processes medication. Some dewormers are safe during these periods; others are not. Your vet assesses your specific cat's health and decides if deworming is necessary or if it should wait until after nursing ends.

What if my cat won't swallow the tablet?

Crush the tablet and mix it with wet food (tuna, chicken, or fish-flavored varieties work best). Some cats accept it in a small amount of butter or cream. Pill pockets (purchased or homemade) work for some cats. If your cat repeatedly refuses the tablet, contact your vet — they may recommend a liquid alternative or topical dewormer instead.

How long does Kiwof take to work?

Worms are paralyzed within 1–2 hours and expelled within 24–48 hours. You may see dead worms in the litter box within 2 days. Full symptom relief (improved appetite, energy, coat) takes 3–7 days as your cat's body recovers from nutrient loss caused by the worms.

Can I give Kiwof with other medications?

Usually yes, but tell your vet about any other medications your cat is taking. Some drugs interact with dewormers. Your vet checks for interactions and adjusts timing if needed (e.g., spacing out doses by a few hours).

What if I accidentally overdose my cat?

Contact your vet or poison control immediately. Overdose symptoms include tremors, excessive drooling, difficulty breathing, or seizures. These are rare but serious. Your vet can provide supportive care (IV fluids, monitoring) until the medication clears your cat's system.
