How to Use Revolution (Selamectin) - Large Cats (Blue)

Keeping your cat healthy isn’t just about good food and regular vet visits—it’s also about protecting them from parasites that can seriously harm their health. Revolution (Selamectin) is a popular, vet-recommended treatment designed to shield your feline friend from fleas, worms, mites, and even heartworm disease. If you’re a cat parent to a large cat, the Revolution Blue pack is the one made specifically for your pet. But how exactly do you use it? Let’s walk through everything you need to know.

What is Revolution (Selamectin)?

Revolution is a topical, once-a-month treatment that uses the active ingredient Selamectin. When applied to your cat’s skin, it gets absorbed into the bloodstream and protects against both external parasites (like fleas and ear mites) and internal parasites (like worms and heartworm larvae).

It’s easy to apply, effective, and safe for most cats when used correctly—no wrestling with pills, no messy powders.

Understanding the Revolution (Blue) Pack

Revolution comes in color-coded packs, and each one is for cats of a certain weight range.

Blue pack → for large cats weighing 5.1–10 kg (11–22 lbs).

Other packs exist for smaller cats and kittens, but using the wrong pack size can reduce effectiveness or even cause harm.

So, if your cat is big and fluffy, the Blue pack is the right one.

What Parasites Does Revolution Protect Against?

Revolution isn’t just a flea treatment—it’s a broad-spectrum protector. With one monthly application, it helps against:

Fleas – kills adults and prevents eggs from hatching

Ear mites – treats and prevents infestations

Heartworm disease – prevents deadly heartworm infection

Intestinal worms – effective against roundworms and hookworms

Ticks – in certain regions, it also protects against some tick species

That’s a lot of protection in one little pipette!

Before You Use Revolution on Your Cat

A few things to check before applying:

Your cat should be at least 8 weeks old and weigh more than 5 kg.

Make sure your cat is generally healthy—if pregnant, nursing, or sick, ask your vet first.

Always check your cat’s exact weight before dosing.

Step-by-Step Guide: How to Apply Revolution (Selamectin) – Large Cats (Blue)

Prepare the pipette

Remove one tube from the pack and hold it upright.

Press the cap down to puncture the seal, then remove the cap.

Find the right spot

Part the fur at the base of your cat’s neck, between the shoulder blades.

The skin here is hard for your cat to lick, making it the safest spot.

Apply the solution

Place the tip of the pipette directly on the skin.

Squeeze the entire contents out in one spot.

Tips for easier application

Do it when your cat is calm or sleepy.

Reward them with a treat afterwards to build positive association.

After Application: What to Expect

The liquid may leave the fur slightly damp—this is normal.

Avoid touching the area until it dries.

Don’t bathe your cat or let them get wet for at least 2 hours.

Monitor your cat for a few hours to ensure there are no reactions.

How Often Should You Use Revolution?

Revolution works best when applied once every month.

For year-round protection, apply it every month without fail.

In areas with seasonal parasites, continue treatment during peak months.

Set phone reminders so you don’t forget!

Potential Side Effects and Safety Concerns

Most cats tolerate Revolution well, but a few may show:

Temporary hair loss or irritation at the application site

Mild digestive upset

Lethargy for a short period

Rarely, allergic reactions may occur. If your cat shows serious symptoms like difficulty breathing or severe vomiting, contact your vet immediately.

What to Do If You Miss a Dose

If you forget:

Apply Revolution as soon as you remember.

Resume the monthly schedule from that date.

Don’t double-dose your cat.
