It not only treats and prevents flea infestations past killing developed fleas before they can lay eggs, information technology also prevents heartworms and treats and controls ear mites, roundworms, hookworms, and infestations of blackness-legged (deer), Gulf Coast, and American canis familiaris ticks.

"The actually exciting matter near flea command is there are always new developments in how we can make them better and safer and more effective," Conservative said.

Harper also likes Revolution Plus. "Overall, Revolution has a pretty good track tape," he said. "Information technology's 1 of the most effective topical flea preventions on the market. I'm a fan of Bravecto equally well, it's a longer-lasting flea prevention, constructive against fleas and ticks."

Bravecto as well contains fluralaner, which is in the same drug class as selamectin and sarolaner, and is besides very effective and well-tolerated by cats. However, Bravecto doesn't control equally many parasites, and information technology tin can't be used in kittens under 6 months of historic period.

Revolution Plus is easily applied every xxx days in one spot to the true cat's skin at the base of the neck between the shoulder blades. The liquid medication is a small volume that is captivated and dries chop-chop, leaving no residue behind.

Cons: Not recommended for kittens younger than 8 weeks of age; does not prevent whatsoever parasites other than fleas, ticks, and chewing lice

Nosotros recommend Frontline Plus because it not just kills fleas and controls flea infestations, but it too kills ticks and chewing lice. Used and trusted by pet owners for more than 20 years, Frontline Plus protects for xxx days with one application. Fleas do not accept to bite your cat for Frontline Plus to work — they die on contact.

Frontline Plus has active 2 ingredients, fipronil and South-methoprene, which work together to kill parasites and interruption the flea life wheel. Fipronil kills adult fleas and ticks, while S-methoprene is an insect growth regulator that prevents the development of young flea stages (eggs, larvae, and pupae). Even so, information technology tin can sometimes have a piffling time of consequent utilise before all fleas are completely gone, especially if your cat was heavily infested, since flea eggs can be present in your habitation but not on your cat.

"In flea-infested environments, when they do studies looking at the efficacy of these products, sometimes it takes a few months of consequent, high-quality flea prevention to even run across that population completely eradicate because there'southward four dissimilar stages to the flea life bicycle," said Conservative.

Frontline Plus is easy to use. Squeeze the entire contents of the tube onto one spot on the cat'due south skin between the shoulder blades. The liquid medication spreads across your cat'due south pare and is stored in the oil glands. It cocky-distributes continuously through the hair follicles for one calendar month.

Comfortis Chewable Tablets first killing fleas within xxx minutes and offer a full month of protection with one easy-to-give flavored pill.

Pros:Fast-acting treatment starts killing adult fleas within xxx minutes, safe for kittens fourteen weeks or older, easy to requite alone or in food

Cons:Does not kill flea eggs or larvae or prevent parasites other than fleas, not labeled for use in kittens younger than 14 weeks or breeding, significant, or nursing cats

Our top choice for an oral flea control product for cats, Comfortis Chewable Tablets, is fast-acting and skillful for cats that tin't tolerate topical flea preventives. Its active ingredient, spinosad, starts to piece of work inside 30 minutes and kills 98% of adult fleas on cats within 4 hours.

Although topical flea control products are typically easier to use (no need to convince your cat to eat a pill), at that place are some cases when an oral preventive is a meliorate choice. For instance, some cats with sensitive peel can't tolerate a spot-on treatment. "An oral flea preventive product is better if a cat has had focal pilus loss related to the application of a topical product or if it has a severe flea-related allergy," said Sawyer.

Harper also recommends an oral product for cats that have very sensitive skin or those that have a lot of irritation. "Comfortis is i of the ones I like," he said. "Information technology's harder to get the cat to take an oral production, but if you can manage it, information technology'southward a pretty effective oral flea medication. It'due south strictly and solely for fleas."

Comfortis is one of two oral flea control products bachelor for cats; the other is Capstar Flea Control Tablets. Unlike Capstar, which kills fleas for merely 24 hours, Comfortis protects cats confronting fleas for a full month. Withal, Comfortis is not safe for kittens younger than 14 weeks sometime. Capstar is safe for kittens as immature as four weeks, so it's our choice for best flea control product for kittens (read more most Capstar in our slide for the best flea control product for immature kittens). In lodge to purchase Comfortis, you volition need a prescription from your veterinarian.

The beefiness-flavored flavored tablets should exist given with food once a month. You can offer them alone just before or after feeding your cat, or hide them in a small amount of food.

The all-time flea command for immature kittens

Pros:Prophylactic for kittens four weeks of age or older, safe for pregnant and nursing cats, fast-acting treatment, like shooting fish in a barrel to give solitary or in nutrient, can exist used with other flea command products, available without a prescription

Cons:Does not offering long-term protection, does non impale flea eggs or larvae, does not forestall any parasites other than fleas

Bachelor without a prescription, Capstar is the simply flea control product safe for kittens equally young equally 4 weeks and weighing at least two pounds. With other flea control products, whether topical or oral, kittens must exist at least viii weeks onetime, and sometimes older.

Fleas should be eliminated every bit speedily every bit possible for heavily infested cats, especially young kittens. The active ingredient in Capstar, nitenpyram, works within 30 minutes and kills greater than 90% of adult fleas in as fiddling as six hours.

Capstar merely protects against fleas for 24 hours, but information technology is safe to requite daily if necessary. Since giving a true cat a pill every day tin be inconvenient, pet owners should follow upwards with a long-term flea control product (a spot-on or oral preventive that lasts a month or longer) once the kitten is old plenty.

The best flea neckband

Seresto/Business concern Insider

The Seresto Flea and Tick Collar offers viii months of protection confronting fleas and ticks in all life stages.

A March 2021 investigation by USA Today reported i,700 animal deaths and other adverse reactions linked to Seresto flea collars. It'due south unknown if the EPA-approved pesticides used in the collar caused these incidents and this story is still developing. Read "Tin can a flea collar harm your true cat?" for more details. E'er speak to your veterinarian if you have concerns before using a product and just purchase Seresto collars from authorized retailers.

Pros: Eight months of protection against adult fleas, flea larvae, and ticks; sustained release technology for continuous protection; lightweight and easy to vesture; adjustable for cats of all sizes; fleas don't have to bite for it to work

Cons: Not recommended for kittens younger than x weeks of age, children should not play with the collar or put it in their mouth, adjusting size can be catchy

Although flea collars were once a standard pick for flea control, these days they accept a back seat to topical and oral preventives. Withal, 1 standout in the flea neckband category is the Seresto Flea and Tick Neckband, which uses patented sustained-release engineering science to provide eight months of continuous protection against adult fleas, flea larvae, and ticks.

In general, topical spot-on preventives and oral preventives are the easiest and most effective course of flea control for cats, merely there are instances when the Seresto neckband might be a good option. "It would be a better choice if compliance is an consequence, every bit you exercise not demand to remember to apply information technology monthly," Sawyer said. "Additionally, information technology is a ameliorate choice if the cat does not tolerate topical flea products and/or information technology is difficult to administer pills."

Bourgeois said that the Seresto collar might also be a good choice for cats that roam outside a lot. "We have some people who accept truly outdoor cats," she said. "They might not see them reliably all the fourth dimension to requite them a monthly product. [The Seresto neckband] would be the simply collar that I would be trusting of."

Although the EPA is currently conducting a review of the safety of the Seresto collar, Harper doesn't think pet owners necessarily need to stop using the neckband if it's the best class of flea control for their cat. "We'll look and see what this review actually brings to light," Harper said. "The jury is still out. If you absolutely can't use any other form of flea preventive, I know the fleas are going to be a problem, so let'due south preclude that."

The collar is nongreasy, smell-complimentary, lightweight, and adjustable for cats of all sizes. It can be worn alongside your cat'south existing neckband and is designed with a ii-step safety system to ensure your cat will not exist harmed if the collar becomes snagged on something.

It kills 100% of fleas within 24 hours of placing the collar on your cat. The neckband is water-resistant and can remain on the cat even when bathing.

  • Bravecto Topical Solution for Cats: Bravecto is a topical product that uses fluralaner to kill fleas and ticks. Dissimilar most topical preventives, which must be applied monthly, one awarding of Bravecto kills fleas for three months and kills ticks for two months.

Our best overall pick, Revolution Plus, is prophylactic for kittens 8 weeks or older, and also treats and controls heartworms and ear mites, which Bravecto does not. Additionally, Bravecto's label states that children should not touch the application site until dry; Revolution Plus has no such warning. For those cat owners who are mainly looking for protection against fleas, Bravecto is a great choice due to its long-lasting protection. Bravecto should be used Bravecto should be used with caution in cats with a history of neurologic disorders such as seizures.
  • Bravecto Plus Topical Solution for Cats: Bravecto Plus is a topical product that uses fluralaner and moxidectin to kill fleas and ticks, prevent heartworm, and treat roundworms and hookworms. Ane application of Bravecto Plus kills fleas and other parasites for two months, unlike most topical preventives, which must be applied monthly. One downside to Bravetco is it cannot be used in kittens younger than half dozen months old. Our all-time overall choice, Revolution Plus, is safe for kittens 8 weeks or older, and also treats and controls ear mites, which Bravecto Plus does not. Additionally, Bravecto Plus's label states that children should non touch the application site for 2 hours after application; Revolution Plus has no such warning.

  • Revolt: This production contains the aforementioned active ingredient as Revolution (selamectin). Like Revolution, it is applied to the skin once a month. Information technology kills the same parasites equally Revolution. It is manufactured by Aurora pharmaceutical based in Northfield, Minnesota. I recommend Revolution over this version since Revolution is the original, has been on the market longer, and comes from a large, reputable veterinarian pharmaceutical company.

Types of flea control products

Here are the most common flea control products for cats and how they work:

  • Topical preventives: Too called "spot-on" products, topical preventives are corking for both killing fleas and preventing flea infestations. Equally they dry, they spread across the entire body, leaving no rest behind. They are usually applied to the peel in ane spot on the dorsum of the neck once a calendar month.
  • Oral flea control: Oral flea control products, or "flea pills," are given to your cat by mouth to kill fleas. Some oral flea command products impale fleas for up to a month; others must be given more than frequently to proceed killing fleas, as ofttimes equally once a day.
  • Flea collars: Flea collars are worn around the neck, where they deliver flea preventive medication to a true cat'south pare and coat.  Our experts said that topical and oral products are superior to traditional collars because they are more than effective and easier to employ. Yet, at to the lowest degree one flea collar (Seresto) delivers preventive medication for up to eight months, a much longer period than topical applications, making it a viable choice for true cat owners who don't desire to take to apply something every thirty days.
  • Flea shampoos: Flea shampoos kill fleas that are currently on your cat. We do not recommend them since topical spot-ons and oral products are easier to use and more effective. Read more about this in our slide on "What to consider when shopping for flea command products."
  • Flea spray: Flea sprays are practical to the skin and coat. Like shampoos, we do non recommend them since topical spot-ons and oral products are easier to utilise and more effective. Read more in our slide on "What to consider when purchasing flea control products."

Tin can a flea collar harm your cat?

The safety of flea and tick collars has been in the news lately, specifically the bestselling Seresto flea and tick collar, which was developed past Bayer and is now sold by Elanco Animal Health. On March ii, 2021, USA Today and the Midwest Center for Investigative Reporting published a report maintaining that the Seresto neckband has been linked to thousands of agin incidents, including pet deaths and incidents of harm to humans.

The Center for Biological Diversity (CBD) filed a legal petition in April urging the U.Southward. Environmental Protection Agency (EPA) to cancel the registration of the Seresto flea and tick collar. A week later, the American Veterinary Medical Clan (AVMA) published an article addressing the controversy surrounding the Seresto collar. According to the AVMA, Seresto's "manufacturer has defended the collars as condom and effective, and veterinarian experts say they have seen no cause for alert."

Additionally, Elanco published a argument on its website calling the media coverage "misleading" and stating that the company stands past the product. "All data and scientific evaluation used during the product registration process and through Elanco's robust pharmacovigilance review supports the product'south safety contour and efficacy," the statement reads.

On July 12, the EPA announced that it is seeking public annotate on the petition from the CBD requesting that the EPA abolish the registration of Seresto. Public comments volition be collected for 60 days. "In addition, EPA is reviewing the additional information received by Elanco and Bayer and will use it to evaluate if the continued registration of these pet collars withal meets the legally required standard of no unreasonable adverse on the environs, taking into account the economic, social, and environmental costs and benefits of the employ of the pesticide," said Tim Carroll, deputy press secretarial assistant for the EPA. "Upon completing the analysis and assessment, EPA may take further action, if needed."

Regardless of what type of flea-command product you cull for your cat, the EPA urges pet owners to read the entire label earlier using the production, follow all directions carefully, and monitor your pet after handling.

In that location are likewise reports of apocryphal Seresto collars on the market, particularly through online retailers. Petco and Petsmart, major suppliers of pet products, told us that they purchase Seresto collars directly from the manufacturer, Elanco. Information technology's of import to buy from a reputable website, brick-and-mortar store with a guarantee program, or for the most assurance, directly from your veterinarian.

If your true cat has fleas, you want to get rid of them as quickly as possible. Cats that get outside are more probable to choice up fleas, merely fifty-fifty indoor cats tin get them, either from the family dog or when they become to the veterinarian or a boarding facility. Fleas can even hitchhike indoors on your apparel or shoes.

What are the health risks to a cat?

Fleas are more than than just a nuisance. These parasites tin pose a threat to your cat'south health. A astringent flea infestation can seriously damage a cat's skin, induce an allergic reaction, or cause them to become bloodless from blood loss. Fleas are also responsible for cats contracting parasites like tapeworms and may transmit diseases.

Signs of fleas in cats include scratching, skin irritation, and the presence of dark red or black specks on your cat's skin, fur, bedding, or furniture. These specks, about the size of grains of black pepper, are called "flea clay" and are flea feces (or digested claret). Back when I worked in the veterinary infirmary, I learned a handy trick to aid detect out if those little specks are regular dirt or flea clay. Scoop some onto a damp newspaper towel. If the paper towel turns red, it's flea dirt.

To check your cat for fleas or flea clay, run a flea comb (a small, very fine-toothed rummage) through your true cat'south coat or part the pilus with your fingers to examine the skin. If you notice whatever alive or dead fleas or flea dirt, your cat has a flea infestation.
