Revolution is a topical parasiticide manufactured by Zoetis, containing selamectin in two weight-based strengths: 15 mg for cats weighing up to 5 lbs and 45 mg for cats weighing 5.1 to 15.0 lbs. A single monthly application to the skin at the base of the neck controls fleas, heartworm larvae, ear mites, roundworms, and hookworms. No prescription is required to purchase Revolution through Anipetshop.
Anipetshop operates as a licensed pharmacy under APVMA regulations in Australia, where selamectin-based topical parasiticides are classified as over-the-counter veterinary products. The selamectin formulation and concentration in products supplied through Anipetshop are identical to prescription Revolution dispensed in the US market.
Can You Buy Revolution for Cats Without a Vet Prescription?
Revolution for cats is available without a veterinary prescription at Anipetshop, a licensed online pharmacy operating under APVMA regulations in Australia.
Whether a prescription is required depends on the regulatory classification applied by the country of supply, not the country of purchase. In the US, the FDA classifies selamectin under the federal prescription drug framework because it acts on the nervous system of both parasites and mammals, and veterinary oversight is required to confirm appropriate use by species, weight, and health status.
Australia’s APVMA evaluates the same compound under a separate risk-benefit framework and classifies selamectin-based topical parasiticides as Schedule 5 or unscheduled veterinary products, permitting over-the-counter supply when the product is correctly labeled and dispensed within defined conditions.
As Anipetshop operates under Australian regulatory jurisdiction, it is legally authorized to supply Revolution to customers in the US without a prescription requirement. The products dispensed are manufactured by Zoetis and contain selamectin at the same concentration and formulation as prescription Revolution sold in the US market.
Explore the Topical Solution Formulation
Revolution for cats is a topical solution containing selamectin, applied once monthly to the skin at the base of the neck. Revolution for cats is supplied as a topical liquid with the following formulation and storage specifications:
- Flavoring: Not applicable. The product is applied to the skin and is unflavored to avoid attracting the cat to the application site or prompting ingestion.
- Key Excipients: Isopropyl alcohol and butylated hydroxytoluene (BHT) as preservative.
- Physical Form: A colorless to yellow ready-to-use liquid solution.
- Storage: At or below 86°F (30°C) in a cool, dry place, out of reach of children.
The following pack options are available at Anipetshop, differentiated by weight range and pack color for accurate dose selection:

Take the Correct Dosage
Revolution for cats is dosed by body weight across three tube strengths, covering cats from ≤5 lbs to 22 lbs. The cat should be weighed before each treatment cycle to confirm the correct tube strength. Age and breed do not determine dose selection.
The table below maps each weight range to the corresponding tube strength and pack color:
|
Cat’s Weight (lbs) |
Tube Strength |
Pack Color |
|
Up to 5 lbs |
15 mg selamectin |
Mauve |
|
5.1–15 lbs |
45 mg selamectin |
Blue |
|
15.1-22 lbs |
60 mg selamectin |
Taupe |
For cats exceeding 15.0 lbs, a combination of tubes is required to reach the minimum effective dose of 6 mg selamectin per kg of body weight, as specified in the product insert.
A cat weighing exactly 5 lbs falls within the mauve tube range (15 mg selamectin), but a cat at 5.1 lbs requires the blue tube (45 mg selamectin). Administering the lower-strength tube to a cat above the weight threshold results in underdosing, which reduces selamectin concentration below the 2.7 mg/lb (6 mg/kg) minimum required for effective parasite control. When a cat’s weight falls at or near a range boundary, weigh the cat on the day of treatment and select the tube that corresponds to the confirmed weight.
Why Cat Owners Should Choose Revolution
Revolution covers five parasite categories from a single monthly topical dose: fleas, heartworm larvae, ear mites, roundworms, and hookworms. Each of the following points reflects a clinically relevant reason for selecting this product over single-target or narrower-spectrum alternatives:
- Heartworm prevention with no feline treatment alternative: No approved treatment exists for adult heartworm infection in cats, making monthly prevention the only viable clinical strategy. Revolution kills Dirofilaria immitis larvae before they mature to the adult stage.
- Simultaneous internal and external parasite control: A single application addresses both ectoparasites and intestinal nematodes, removing the need to administer separate oral anthelmintics alongside a topical flea product.
- Relevant for indoor cats: Fleas and heartworm-carrying mosquitoes enter indoor environments via clothing, footwear, and unsealed entry points. Indoor-only status does not eliminate exposure risk.
- Approved for use from 8 weeks of age: Revolution is labeled for kittens from 8 weeks old, and has been evaluated as safe in breeding, pregnant, and lactating cats, covering the full adult life cycle without a labeled age ceiling.
- Topical application with no oral dosing requirement: The 0.25 ml or 0.75 ml volume is applied directly to the skin at the base of the neck, which avoids the compliance issues associated with oral tablet administration in cats.
How Do Pet Owners Review Non-Prescription Revolution for Cats Online?
Owners who have purchased Revolution through Anipetshop report consistent flea and ear mite control, and note the absence of a prescription requirement as a practical factor in choosing to order online.
Summit Veterinary Care notes that a single Revolution application addresses multiple parasite categories, reducing the need to combine separate medications for different conditions.
Family Animal Hospital (Fort Worth) reports that Revolution’s coverage profile stands out among cat-specific products, particularly for its tick activity, and that topical application removes the handling difficulty associated with oral dosing in cats.

How Revolution Works on Cats
Selamectin belongs to the avermectin class and kills parasites by blocking glutamate-gated chloride channels in nerve and muscle cells, causing paralysis and death in susceptible nematodes and arthropods. After topical application at the base of the neck, selamectin penetrates the skin barrier and enters systemic circulation, reaching active concentrations in the sebaceous glands, skin tissue, and bloodstream. Mammalian cells are not affected at labeled doses because glutamate-gated chloride channels do not occur in vertebrate nervous systems in the same configuration as in parasites.
The mechanism produces distinct outcomes across the parasite categories Revolution is labeled to control:
- Flea control: Selamectin kills adult fleas feeding on the cat and renders post-treatment flea eggs non-viable, interrupting the reproductive cycle and reducing environmental reinfestation.
- Heartworm prevention: Revolution eliminates Dirofilaria immitis microfilariae and fourth-stage larvae before they mature to the adult stage. It is not effective against established adult heartworms, so monthly dosing without gaps is required.
- Ear mite elimination: A single dose is typically sufficient to resolve Otodectes cynotis A second dose at the one-month interval may be necessary in cases of heavy or persistent infestation.
- Intestinal nematode control: Systemic selamectin distribution reaches concentrations effective against roundworms (Toxocara cati) and hookworms (Ancylostoma tubaeforme) in the gastrointestinal tract.
How Should You Administer Revolution for Cats?
Revolution is applied topically to the skin at the base of the neck, with the entire tube contents deposited in a single spot. The application site should remain unwashed for at least 24 hours to allow full dermal absorption. Before starting Revolution in a cat over 6 months of age, heartworm testing is recommended by the American Heartworm Society, as the product does not eliminate established adult heartworm infections.
Follow these steps to administer each dose correctly. Errors in application technique can result in incomplete absorption or accidental oral ingestion by the cat:
- Prepare the tube: Hold the tube upright and press the cap down firmly until you feel a click. This punctures the internal seal. Remove the cap and confirm the tip is open before proceeding.
- Confirm the coat is dry: The cat’s hair must be completely dry at the time of application. Moisture on the skin interferes with selamectin absorption through the skin barrier.
- Locate the application site: Part the fur at the base of the neck, directly in front of the shoulder blades, until the bare skin is visible. Placing the product this far back on the neck reduces the cat’s ability to reach the site with its tongue.
- Apply the full tube contents: Press the tip directly against the exposed skin and squeeze the tube 3 to 4 times in one spot until empty. Do not split the dose across multiple locations.
- Withdraw the tube without releasing pressure: Keep the tube squeezed while gliding it away from the liquid on the skin before lifting it off. Releasing pressure before withdrawal causes the tube to draw product back up. Discard the empty tube immediately.
Are There Any Side Effects of Revolution for Cats to Consider?
Revolution is well tolerated in most cats at labeled doses, with the majority of reported adverse effects limited to the application site or transient gastrointestinal signs. The following side effects have been identified in clinical and post-market data:
- Application site reactions: Temporary hair loss or mild skin irritation at the treated area is the most commonly reported local reaction and typically resolves without intervention.
- Hypersalivation: If the cat contacts the application site before the product has dried, oral exposure to selamectin causes excessive drooling. This is a response to the compound’s taste rather than systemic toxicity.
- Gastrointestinal signs: Vomiting or diarrhea occurs rarely and is typically self-limiting. If signs persist beyond 24 hours, veterinary evaluation is indicated.
- Transient appetite or behavioral changes: Mild, short-duration reduction in appetite or drowsiness has been reported. These signs resolve without treatment in most cases.
- Safety margin at overdose: In controlled studies, Revolution was administered at 10 times the labeled dose in kittens without adverse reactions, establishing a wide safety margin at standard doses.
- Neurological history: Cats with a history of seizures or neurological disorders should be assessed by a veterinarian before beginning selamectin treatment. Avermectin-class compounds act on chloride channel conductance in the nervous system.
- Drug interactions: Revolution has been used concurrently with vaccines, anthelmintics, and antibiotics in clinical studies without identified interactions under standard treatment protocols.
Are There Revolution Alternatives Without a Vet Prescription?
Several topical parasiticides covering overlapping parasite categories to Revolution are available without a prescription at Anipetshop. The alternatives below differ in active ingredient combination, parasite coverage, and dosing interval:
- Advocate: Covers fleas, heartworm, ear mites, roundworms, and hookworms on a monthly schedule. Functions as a direct coverage equivalent to Revolution using a different active ingredient combination.
- Stronghold: Contains the same active ingredient as Revolution at the same concentration, making it a bioequivalent alternative for owners seeking identical mechanism and coverage.
- Revolution Plus: Extends the selamectin base with sarolaner, an isoxazoline, to add tick control and coverage of the biting mite Notoedres cati. Indicated for cats in environments with documented tick exposure.
- Bravecto Plus: Administered every 2 months rather than monthly. Covers fleas, ticks, heartworm, roundworms, and hookworms, but does not include ear mite or Notoedres cati
- NexGard Combo: The only option in this group that includes tapeworm coverage via praziquantel. Indicated when tapeworm exposure is a confirmed or probable risk.
FAQs
Do indoor cats really need Revolution?
Yes. Fleas enter indoor environments via other pets, clothing, and footwear. Mosquitoes, which transmit Dirofilaria immitis, enter through open windows and unsealed entry points. Indoor-only status does not eliminate heartworm or flea exposure risk.
How quickly does Revolution start killing fleas?
Revolution begins killing fleas within 12 hours of application and reaches full effectiveness within 24 hours.
Can I use Revolution for dogs on my cat?
No. Revolution for dogs contains selamectin at a higher concentration than the cat formulation, and the inactive ingredients differ. Applying the canine product to a cat carries a risk of overdose. Use only the species-labeled product.
What should I do if I miss a dose?
Administer the missed dose as soon as it is identified, then resume monthly dosing from that new date. Do not double-dose to compensate for the missed interval.
How long does Revolution take to dry?
The application site is typically dry within 2 hours. Drying time varies with coat thickness. Do not touch or wet the application site until it is fully dry.
At what age can Revolution be used in kittens?
Revolution is labeled for kittens from 8 weeks of age. Some regional product labels specify 6 weeks. Check the label of the specific pack before administering to kittens under 8 weeks.
Is Revolution safe for pregnant or nursing cats?
Original Revolution has been evaluated and is labeled as safe for breeding, pregnant, and lactating cats. Revolution Plus has not been assessed in these populations. Do not use Revolution Plus in pregnant or lactating cats without veterinary guidance.
What happens if my cat licks the application site?
Oral contact with selamectin before the product has dried causes hypersalivation and may cause vomiting. This is a response to the compound’s bitter taste. If signs persist beyond 30 minutes or the cat shows neurological symptoms, contact a veterinarian.
Can Revolution be used on sick or underweight cats?
No. The manufacturer’s labeling contraindicates use in cats that are sick, weak, or significantly underweight. Consult a veterinarian before treating a cat in compromised condition.
Is Revolution water-fast after application?
Revolution is water-fast 2 hours after application for flea control purposes. Bathing or wetting the coat within 24 hours of application may reduce heartworm prevention efficacy. Wait 24 hours before allowing water contact.
Can Revolution be applied to a wet cat?
No. The coat must be completely dry at the time of application. Moisture on the skin reduces dermal absorption of selamectin.
Why is there a powdery residue at the application site?
Temporary hair stiffening or a white powdery residue at the application site is a normal consequence of the isopropyl alcohol carrier evaporating after application. It does not affect product efficacy or safety.
Should I test my cat for heartworm before starting Revolution?
Cats over 6 months of age should be tested for existing heartworm infection before beginning any preventative. Revolution does not eliminate established adult heartworms, so administering it to a heartworm-positive cat without prior diagnosis does not constitute treatment. Consult a veterinarian for testing before starting the first dose.
