What Revolution Is and How It Works
Revolution® is a monthly, spot-on medicine for cats that targets several parasites. The active ingredient, selamectin, spreads across the skin’s oils after a single application. It then enters the bloodstream at low levels to prevent heartworm disease and reaches tissues where ear mites, roundworms, and hookworms live. On the skin and coat, it kills adult fleas and disrupts the flea life cycle for one month.
Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.
This treatment is prescription-only. It is applied once a month to clean, dry skin at the base of the neck. It does not cover ticks; for tick control, a different product may be recommended. Ask your veterinarian which spectrum best fits your cat’s risks, lifestyle, and any local parasite prevalence.
Who It’s For
Revolution for Cats is indicated to prevent heartworm disease and to treat or control fleas, ear mites, roundworms, and hookworms in cats. It is generally used in cats that are at risk for these parasites, including indoor pets that can still encounter fleas or mosquitoes. Kittens may be started when they reach the labeled minimum age and weight as directed by your veterinarian.
Do not use it in cats with known hypersensitivity to selamectin. If your pet is ill, underweight, or recovering from surgery, consult your veterinarian before starting or continuing therapy. If your cat has had a reaction to another avermectin-like product, discuss that history with your prescriber.
Dosage and Usage
Follow the labeled Revolution dose for cats based on weight. Use the premeasured single-use tube that matches your cat’s weight band. Part the hair at the base of the neck, place the tip of the tube directly on the skin, and squeeze to empty the entire contents in one spot. Do not massage the site. Avoid contact with the application area until dry.
Apply once every month, year-round or during your veterinarian-advised season. Do not bathe your cat immediately after applying; allow the product to dry. If grooming or licking occurs right away, transient drooling may be seen due to the bitter taste. Keep this medicine away from children until the application site is dry.
Strengths and Forms
This medicine comes as single-use topical tubes in weight-based presentations for cats. Packs are color-coded by weight ranges, such as up to 5 lb, 5.1–15 lb, and 15.1–22 lb. Availability may vary by lot or market. Your veterinarian will select the appropriate size for your cat’s current weight and health status.
Some pet owners ask about Revolution for kittens; veterinarians typically start selamectin when kittens reach the labeled minimum age and weight. Always follow your prescriber’s guidance on when to begin and how to size the tube as the kitten grows.
Missed Dose and Timing
If you miss a monthly dose, give it as soon as you remember and resume the monthly schedule from that date. Do not double up doses. If you live in a heartworm area and are significantly late, ask your veterinarian about testing and next steps. Consistent monthly use is important to prevent gaps in protection.
Storage and Travel Basics
Store tubes at typical room conditions away from heat, open flame, and direct sunlight. Keep the tubes in their original foil pouches and out of reach of children and animals. Do not puncture or open until you are ready to use. When traveling, pack the next month’s dose in a secure pouch with your prescription label or receipt. Consider setting calendar reminders so you do not miss a monthly date while away. For air travel, place tubes in a sealable bag and keep them in carry-on luggage to avoid temperature extremes. A micro tip: encrypted checkout protects your details when you order.
Benefits
This class of medicine offers broad-spectrum protection in a simple monthly application. It helps prevent heartworm disease, kills adult fleas, controls ear mites, and treats two common intestinal parasites in cats. Many owners prefer a single product to manage multiple risks. The treatment is applied on the skin, which avoids giving a pill to reluctant cats. Veterinarians may choose it for cats that need comprehensive parasite control without tick coverage.
Side Effects and Safety
- Application site effects: temporary hair clumping, mild redness, or flaking
- Behavioral signs: brief drooling or lip-smacking if licking occurs
- Digestive upset: occasional soft stool or decreased appetite
- General: rare lethargy or itchiness
Serious reactions are uncommon. Rare neurologic signs have been reported with macrocyclic lactones in susceptible animals. Seek veterinary attention for persistent vomiting, severe lethargy, tremors, or if your cat ingests the contents. Use only as directed for cats; do not apply dog products to cats. Report adverse events to your veterinarian.
Drug Interactions and Cautions
Tell your veterinarian about all parasite preventives, supplements, and medicines your cat receives. Using multiple topical ectoparasiticides together can increase skin irritation. Combining macrocyclic lactones should be monitored by a prescriber. The label ingredient is widely referenced as Selamectin cat in clinical resources; your veterinarian can confirm compatibility with other therapies based on your cat’s health and weight.
Use caution with very small or debilitated cats. Do not apply on broken skin. Keep treated animals separated until the application site is dry to prevent accidental contact transfer to other pets or people.
What to Expect Over Time
After the first monthly application, you may notice fewer adult fleas on your cat and improved comfort. Ear mite-related scratching can lessen as infestations are treated. Roundworm and hookworm control aligns with the label, though your veterinarian may advise periodic fecal checks. In heavy flea environments, you may still see fleas for a time as pre-existing pupae emerge; consistent monthly use and environmental hygiene are important.
Set reminders for the same day each month. If you bathe your cat for medical reasons, allow adequate drying time after the application before bathing. Schedule follow-up visits to review prevention strategies and adjust plans if your cat’s lifestyle changes.
Compare With Alternatives
Some cats need broader or narrower coverage depending on local risks. For rapid flea knockdown during an acute outbreak, your veterinarian may consider a short-course oral like Capstar For Cat Dog. For a heartworm-focused oral preventive that also targets select intestinal parasites, your clinic may recommend Interceptor Flavour Tabs Cats Dogs. Your prescriber can help match the spectrum to your cat’s needs and the parasites in your area.

Pricing and Access
Cash-pay pet owners often ask about the Cost of Revolution for cats. Our goal is to provide clear options so you can compare pack sizes and plan refills with your veterinarian. Because this product is sourced at Canadian rates, many customers see predictable monthly costs.
Check current pricing, verify your prescription, and choose a pack suited to your cat’s weight band. Fulfilment is through Canadian partners and Ships from Canada to US. You can place your order through a secure account; details are protected during checkout and storage.
Availability and Substitutions
Supply can vary by weight band or packaging. If a size is temporarily unavailable, your prescriber may suggest an appropriate alternative within the same class or another preventive with a comparable spectrum. Any change should be reviewed to ensure the parasite coverage still fits your cat’s risks.
Patient Suitability and Cost-Saving Tips
This medicine may suit healthy adult cats and kittens that meet the label’s minimum age and weight. It can be considered for indoor cats in areas with mosquitoes or where fleas are common. Cats with a history of skin sensitivity at topical sites may need a different option or additional grooming measures.

What parasites does this monthly topical cover for cats?
It prevents heartworm disease and treats or controls several common parasites in cats. Those include adult fleas, ear mites, roundworms, and hookworms, according to the label. It does not address ticks. Your veterinarian may recommend adding or switching to a different product if tick exposure is a concern. Keep using prevention consistently throughout the season your clinician advises. Discuss regional risks so your plan fits local parasite patterns.
How do I apply the tube correctly on my cat?
Part the hair at the base of the neck until you can see the skin. Place the tube tip directly on the skin and squeeze to empty the entire contents in one spot. Do not massage the area. Allow the site to dry before touching your cat. Avoid bathing immediately after use. If your cat licks the wet site, you may see brief drooling due to taste. Contact your veterinarian if signs persist or worsen.
When can kittens start monthly selamectin?
Veterinarians typically start selamectin when kittens reach the label’s minimum age and weight for the smallest presentation. Your prescriber will confirm the right timing based on growth and health status. As kittens gain weight, the tube size may change. Keep a consistent monthly schedule and ask about fecal checks for intestinal parasites. Never split or combine tubes unless your veterinarian has instructed you to do so.
What if I miss a month or apply it late?
Give the missed dose when you remember, then continue monthly from that new date. Do not give two doses at once. If you live in an area where heartworm is present and you are significantly late, contact your veterinarian for guidance on testing and next steps. Staying on schedule helps maintain protection across parasite life cycles and keeps coverage consistent through seasonal changes.
Are there side effects I should watch for after application?
Mild and temporary skin effects at the application site can occur, such as clumping or redness. Drooling can appear if a cat licks the wet product because it tastes bitter. Less commonly, cats may seem tired or have soft stool. Serious reactions are rare, but seek care if you see persistent vomiting, severe lethargy, tremors, or unusual behavior. Keep the tube and wet application site away from children and other pets until dry.
Can I use other parasite products with this one?
Tell your veterinarian about any topical or oral preventives you already use. Combining multiple ectoparasiticides can increase the chance of skin irritation. Products in the same macrocyclic lactone class may require monitoring when used together. Your clinician will match the spectrum to your cat’s needs and may recommend a single product to simplify your routine and reduce overlap.
How should I store and pack it for travel?
Keep tubes at typical room conditions away from heat and direct sun. Store them in the original foil pouch and out of reach of children and pets. For travel, place the next month’s dose in a sealable bag with a copy of your prescription label or receipt. Keep it in carry-on luggage to avoid temperature extremes. Set calendar reminders so you do not miss a monthly dose while you are away.
