Frequently asked questions
How Quickly Does Revolution Plus Start Working?
Revolution Plus begins killing fleas within 6 hours of application and starts killing ticks within 24 hours, achieving over 90% tick efficacy within 48 hours. It also achieves over 99% efficacy against ear mites after a single dose.
What Parasites Does Revolution Plus Protect Against?
Revolution Plus provides 6-in-1 protection covering fleas, ticks (black-legged tick, American dog tick, Gulf Coast tick, and Lone Star tick), ear mites, heartworm, roundworm, and hookworm — all in a single monthly application.
What Is the Difference Between Revolution and Revolution Plus?
Regular Revolution contains selamectin only and protects against fleas, heartworm, ear mites, roundworms, and hookworms. Revolution Plus adds sarolaner, significantly expanding tick coverage to include four tick species — black-legged tick, American dog tick, Gulf Coast tick, and Lone Star tick — making it a more complete solution for cats and kittens with any outdoor exposure or in tick-prone areas of the USA and Canada.
Do I Need a Prescription to Buy Revolution Plus in the USA or Canada?
No. Smartway Pet Supplies ships genuine Revolution Plus from Australia, where it can be legally supplied without a prescription. Customers in the USA, Canada, and other countries do not need a vet visit or prescription upload to place an order — simply select your cat's weight range and checkout.
Is the Yellow Pack the Right Size for My Cat or Kitten?
The yellow pack is designed for cats and kittens weighing 2.8–5.5 lbs (1.25–2.5 kg). It is the smallest variant in the Revolution Plus range and is ideal for kittens and petite adult cats. If your cat has grown beyond 5.5 lbs, move up to the orange medium cat pack to ensure they receive the correct dose. Revolution Plus should not be given to kittens weighing less than 2.8 lbs or under 8 weeks of age.
How Do I Apply Revolution Plus?
Firmly press the cap down until you hear a click to puncture the seal, then remove the cap. Part the fur at the base of the neck between the shoulder blades until the skin is visible, and squeeze the entire contents of the tube directly onto the skin in one spot. Avoid contact with the eyes and wash hands thoroughly after application.
Does Bathing or Swimming Affect Revolution Plus?
Revolution Plus is water-resistant once dry. For best results, avoid bathing your cat for 2 hours after application and allow the product to fully dry before any water exposure.
How Often Should I Apply Revolution Plus?
Revolution Plus is applied once every 30 days. For heartworm prevention, apply monthly year-round — particularly important in warmer US and Canadian regions where mosquito season is extended.
Is Revolution Plus Safe for Kittens?
Revolution Plus is approved for use in cats and kittens from 8 weeks of age weighing at least 2.8 lbs. The yellow pack delivers the correct low doses of selamectin and sarolaner for the smallest cats and kittens. Note that the safe use of Revolution Plus has not been established in breeding, pregnant, or lactating cats — consult a veterinarian before use in these cases. Use with caution in cats with a history of neurologic disorders, as sarolaner belongs to the isoxazoline class which has been associated with tremors, ataxia, and seizures in rare cases.
