Catego vs Revolution Comparison

Both Catego and Revolution can be used to eliminate a flea infestation in your feline. However, each one of them has distinctive features and works according to a different mechanism. In this section, we analyze the features of each treatment and compare them to help you pick the right one for your cat.

Target Microorganisms

Catego Flea and Tick Control for Cats (6 Pack), 1.5 lb/One Size

Catego is an efficient treatment that targets fleas and chewing lice. Revolution has a broader spectrum as it kills fleas and prevents heartworms. Moreover, it eliminates ear mites, roundworms, and hookworms.

Both treatments can be used to prevent a current infestation from spreading. Once applied, both treatments can deliver long-term protection.

Active Ingredients

Although both Catego and Revolution are efficient treatments, they contain different active ingredients that eliminate fleas according to different mechanisms.

Dinotefuran, Pyriproxyfen, and fipronil in Catego combine together to stop the fleas’ life cycle. The formula kills the adult fleas and slows down the growth of the offspring, and ultimately kills them. It also kills dormant eggs and protects against future infestation.

Selamectin and Sarolaner are the active ingredients in Revolution. Selamectin is a potent treatment that prevents the infestation of heartworms when your pet is exposed to the Dirofilaria immitis larvae.

When Revolution is applied to the cat’s skin, both the Selamectin and Sarolaner get absorbed by the skin and travel through the bloodstream. They get rid of fleas before they start laying eggs.

How Do They Work?

Catego and Revolution are both topical treatments applied to your cat’s skin to get rid of fleas. Catego can be applied to the skin and starts showing results within 6 hours of application. Within the first 3 hours of application, Catego achieves about 97% efficiency.

Ideally, you should apply it once per month for protection, but you can apply it more often in case of a serious infestation. Catego arrives in packs of 1, 3, or 6 doses.

Revolution is a topical treatment that gets absorbed by the cat’s skin. The active ingredients kill adult fleas and other parasites like heartworms.

Within the first 36 hours, you can start seeing the results of Revolution, but it starts killing fleas within 6 hours. It comes in packs of 6 doses and should be applied monthly to prevent flea infestations.

Both Catego and Revolution come in easy-to-use tubes. You need to locate the infected spot, which is usually located on the neck, and part the cat’s fur to apply the treatment directly to the skin to allow for the best absorption.

Catego Flea and Tick Control for Cats (6 Pack), 1.5 lb/One Size

Catego can be used safely by kittens after the age of 8 weeks. Medicated, pregnant, and lactating cats shouldn’t use Catego.

Catego’s dosage should be applied monthly, even in the case of a severe infestation. Since it’s fast-acting, you can start seeing results within hours.

One application should be applied for a full-size cat that weighs above 1.5 pounds. You should wait and monitor your feline. If you see that the infestation hasn’t improved or disappeared, you can apply another dose after one month.

Revolution can be used on kittens that are 6 weeks or older. However, the safe use of Revolution by pregnant or lactating cats hasn’t been evaluated.

Revolution’s dose is determined by the vet based on the cat’s weight. One dose is enough for a cat that weighs 2.8 pounds, and you can add more dosages for bigger cats. Since it travels through the bloodstream, you shouldn’t exceed the dosage to prevent the occurrence of side effects.

Side Effects

Although Catego is safe to use by most cats, some felines show allergic reactions due to sensitivity to one of the ingredients. If your cat is sensitive to any of the active ingredients, it might experience some uncomfortable symptoms like redness, itchiness, scratching, vomiting, and general discomfort.

After applying Catego to your cat’s skin, you should monitor it closely to make sure that there is no adverse reaction. If your cat starts showing sensitivity symptoms, you should bath it using a generous amount of water and a gentle cat shampoo to remove the treatment from the cat’s skin and fur. If the cat keeps on showing signs of discomfort, you should take it to the vet.

Revolution has some rare side effects but is generally safe for use. Almost less than 1% of the cats experienced digestive issues and discomfort after the application of Revolution. In other rare cases, there was a temporary hair loss where the treatment was applied. Nevertheless, the hair grew back within months, and there were no permanent side effects.

Other temporary side effects that your cat might experience include the clumping of fur or a change in its texture. In most cases, the cat’s fur can become too stiff and weak. The skin and the fur could show some minor discoloration, which might get worse if the treatment was repeated. A powdery residue is quite common, but it’s easy to rinse later.


1. How Many Fleas Count As An Infestation?

Finding a flea or two might not be a severe problem. However, if you can see more than 20 fleas on your cat’s body, then this is an infestation that shouldn’t be taken lightly. In some cases, the number of fleas can increase to reach 200 or 300 within a few days.

2. How Do Cats Catch Fleas?

Fleas are annoying parasites that can infect your feline’s body in multiple ways. If your cat spends time outside the house, a flea can travel on its body and start to lay eggs that hatch, and the fleas multiply in a very short period.
In some cases, you might be the reason why your cat got fleas. The fleas can jump on your clothes and then jump onto your cat’s body. If your cat has been playing with another pet, the fleas can jump from the other animal’s body to yours.

3. How Fast Do Fleas Multiply On The Cat’s Body?

Fleas multiply rapidly, as long as there’s no treatment that breaks their reproductive cycle. An adult flea can lay between 20 and 50 eggs per day as soon as it reaches maturity. This means that within one month of infestation, each flea can produce up to 1500 fleas that continue the cycle.
This is why it’s crucial to apply a potent and fast-acting treatment that either kills the flea at all stages of the life cycle or kills adult fleas and prevents the younger offspring from reaching sexual maturity. In most cases, flea treatments should be applied as monthly preventive treatments to keep fleas at bay.

4. How Can You Tell That Your Cat Has Fleas?

There are several signs that your cat has fleas.
– Fleas cause skin irritation and itching. If you see that your cat is scratching and licking its body all the time, you need to check its body to see if there are fleas. Keep an eye on excessive scratching because it’s a tell-tale sign.
– Your cat might be biting itself. This is a sign of huge discomfort that is usually related to a serious flea infestation.
– Skin problems and hair loss are side effects of a serious flea infestation that was not treated. Your cat might be allergic to the saliva of fleas which cause hair loss.
– Your feline might be too uncomfortable and might show signs of aggressiveness. Keep an eye on any change in behavior.
– Flea dirt or black specks show you that your cat is suffering from a flea infestation. Flea dirt is made of flea waste and the undigested blood that the fleas have absorbed from the cat’s body. However, it’s only visible when the flea problem has been ignored for a while.
– In severe cases, your cat might develop pale gums because of blood loss. Flea anemia is more common in kittens because of their small bodies.

Wrap Up
