Best Cat Flea Treatment

Indoor and outdoor cats both need the best cat flea treatment in order to ensure that they aren’t bothered by the pesky insects.

Flea treatments, flea and tick products, and even heartworm prevention options are well worth it because they extend your cat’s lifespan and keep them happy, too.

Outdoor cats are definitely different than their indoor cousins. While they still have many of the same needs – kitten food or cat food, a full water bowl or access to a cat water fountain, a comfy cat bed to sleep in, or the ability to enjoy their automatic cat feeder – they experience life a bit differently.

For example, an outdoor cat (or even a cat that is indoor/outdoor) has no need for a regular cat litter box or an automatic cat litter box, cat litter mat, or even cat litter. They can go outdoors! Cats that are used to being outside usually have a cat collar with ID, but rarely use a cat leash or cat harness.

Their need for a cat tree or cat toy is diminished because they have the entire outdoors to play in. They can scratch trees and the ground, so they don’t need a cat scratching post or cat scratching pad. And, if you have a garden, they can get their catnip from there.

But, their veterinary care is something that doesn’t change whether a cat is indoors or outdoors. You still need to put them in a cat cage or cat carrier, and they may need a cat cone if they have surgery or an injury.

While at the vet, you also want to be sure they have the best cat flea treatment possible. Any cat that goes outside is susceptible, and indoor cats aren’t safe either as fleas are notorious for finding their way into even the cleanest of homes.

Dealing with a case of fleas in your home can take every ounce of energy to fight and makes a cat very uncomfortable.

Getting the appropriate cat flea treatment can control these stubborn pests and provide relief to your entire household.

Fleas are very resilient and spread fast. They don’t need much time to completely infest a kitten or cat – this is why a flea medicine needs to act quickly.

You also want to look for something that is easy to apply or administer. Cats are already unhappy from the fleas, the medicine shouldn’t add to it.

The right choice will return a cat’s health and happiness.

Cheristin is a non-prescription treatment that is easy to apply and kills as well as protects against fleas. No matter the size of your kitty, just one dose can take care of their flea issue.

Besides being designed for cats, it also only targets the problem of fleas so you don’t have to worry about any extra ingredients being added that may be addressing a problem your kitty doesn’t even have.

Very effective and long-lasting, fleas will be taken care of, providing comfort to your cat. Use it to treat fleas or as a prevention medicine to ensure fleas never become a problem. This is one of the best targeted solutions to help felines suffering from this insidious pest.

Pros

The rounded-tip applicator makes this an easy topical flea cat treatment. The rounded tip is gentle on the skin while making the entire process much less messy.

Some flea medicines have strong formulas meant to handle issues that go beyond having fleas. If you need a flea killing treatment that is mild and gentle, yet effective to bring relief to your furry one, this Cheristin treatment is the one for you.

  • Effective formula: Spinetoram, an insecticide, is the powerful active ingredient that makes this treatment work so well. It combines the effectiveness of fipronil and imidacloprid, both commonly used cat flea treatment ingredients. After applying it, fleas are gone for up to six weeks before another dose is required.
  • Cats feel relief quickly: Having fleas is an awful experience for your feline friend so get them a cat flea treatment that works quickly. This treatment starts killing fleas within 30 minutes of being applied. Within 12 hours, 98-100% of fleas are gone.
  • Your cat’s nose will thank you: The smell of this cat flea treatment by Cheristin is pleasant, much better than the way flea treatments commonly smell. The lack of a foul chemical odor means that when you apply it to a cat, the smell won’t stress them out any further.
  • Safer option for flea removal: A more natural flea treatment for cats compared to more well-known brands, it has ingredients that are not too harsh on cats. Thanks to the gentle formulation, it can be used simultaneously with other insecticides without reactions to other chemicals.
  • Easy application: The rounded-tip applicator makes this an easy topical flea cat treatment. The rounded tip is gentle on the skin while making the entire process much less messy. Detailed instructions are included that clearly explain how to handle the product.
  • Specially designed for cats: Formulated especially for cats, there’s no need to worry if it is unfit for your feline. It can be used on any cat older than 8 weeks and weighing over 1.8 pounds, making it one of the most recommended cat flea treatments from vets.

Cons

Cat owners enjoy this Elanco product because it is easy to apply without making a mess and brings relief fast, but it does have a few issues. Before you decide if it is right for your pet, here are a few things you should know.

  • Best for indoor cats: Though it contains an effective flea-killing formula, it only keeps fleas away on cats that spend most of their time inside. Outdoor cats will find relief from the fleas that are on their skin, but it will be for a much shorter amount of time.
  • Doesn’t kill all fleas: Spinetoram is a mild insecticide that controls and treats adult flea infestations. This means that it doesn’t eradicate fleas in their other life stages – the eggs, larva and pupa left behind will still have to be dealt with or they can become a problem.
  • Side effects can be unpleasant: The less harsh ingredients still have a chance of causing unwanted effects on felines, especially since cats lick their fur and can accidentally ingest it. Some side effects to be aware of are hair loss at the area of application and nausea.

Not only does it eliminate fleas and ticks within 24 hours, it attacks every life stage a flea goes through. This means that adult fleas as well as the eggs and larvae are taken care of with one product.

If you have any problems with the product, get your money back. PetArmor stands behind everything they make 100% and deliver quality customer service.

Great for indoor and outdoor cats, the waterproof formula is guaranteed to work.

Pros

This is one cat flea treatment option that eliminates the risk by killing off fleas in every life stage so they can’t reach adulthood and harm your pet.

Often people think that name brands work better than lesser known ones, but this is not always the case. PetArmor offers cat owners the chance to get high quality anti-flea and tick treatment for less than the more well-known brands.

  • Gets rid of fleas & ticks: Cats will be much more comfortable after using this cat flea treatment with fipronil as its main active ingredient. The fipronil is released through the top layer of the skin to kill parasites and then works to prevent new ones from attaching.
  • Combats various stages of fleas and controls other pests: Another important ingredient found in this cat flea treatment liquid is s-methoprene. This ingredient acts as a backup to the main one (fipronil), killing off parasites that have survived the initial application, such as stubborn flea species and chewing lice.
  • Prevents reinfestation: Left behind flea eggs, larva and pupa can reinfect a cat. This is one cat flea treatment option that eliminates the risk by killing off fleas in every life stage so they can’t reach adulthood and harm your pet.
  • Waterproof: This is one of the better cat flea treatment products for outdoor pets because it continues to stay active even when the cat is wet. Now you can let them go outside without worrying if they will come back with fleas.
  • Comparable to more well-known brands: This anti-flea treatment holds up well in a cat flea treatment comparison with the leading brands. It has the look and feel of a name brand with a smaller price tag. For those looking for a cost-effective option that works, this is it.
  • Safe for cats: As far as cat flea treatment side effects go, this PetArmor product has minimal unwanted effects on cats. There have been few reports of any serious allergic reactions, rashes or burns. The formula is gentle enough to keep working on any pet.

Cons

Affordable, effective and safe, cats will be able to find relief when you apply PetArmor Plus anti-flea treatment to their skin. Depending on the level of the infestation you’re dealing with, though, it does have some shortcomings that may impact your purchase decision.

  • Not easy to apply: Instead of snapping or twisting, the tubes have to be cut open. The treatment is a bit watery so it’s important to carefully apply it so it doesn’t leak all over. A little bit of planning can make the application process a bit smoother.
  • Relief is not immediate: If your kitty is in need of immediate relief, this product doesn’t work that quickly. While other brands start attacking instantly, you won’t see fleas instantly and visibly falling off your pet. It takes some time – from 1 to 2 days – to start working.
  • Reapplication may be needed in less than 30 days: This product may not provide a full 4 weeks of protection. After about 3 weeks, a little bit less time than expected, fleas and ticks might be seen coming back.

  • Be careful with application: When applying the treatment to your pet, use the applicator tip to make a thin 3-4 inch thin line between the shoulder blades. Do not apply on the neck or in one area. It can cause chemical burns, hair loss or sores and rashes.

Fleas and ticks are a nuisance and take a lot of work to get rid of. If something isn’t done quickly, the infestation will become a health hazard for not only cats, but humans too.

An effective cat flea treatment will help.

Flea collars are one way to treat and prevent pest infestations that cats are at risk of catching.

Fortified with insecticides released in non-toxic doses, they offer protection that lasts much longer than other flea treatments.

Collars are easy to use, but the one you choose must be comfortable and safe enough that your furry kid won’t try to scratch it off or hurt themselves while playing.

Information

The insecticides provide a great defense against ticks and fleas, killing them on contact.

A flea collar is a popular choice because it offers felines long lasting protection from fleas without much maintenance. The Bayer Seresto Collar Tick & Cat Flea Treatment is one of the most reliable collars available and is just as effective as drops and sprays.

Some collars use a cat flea treatment of essential oils to keep pests at bay, this one uses two insecticides: imidacloprid and flumethrin. Though it may be less organic than essential oils, it is very safe for your pet. The ingredients used in this product have been tested rigorously and are certified to be safely used on cats and young as 10 weeks old.

The insecticides provide a great defense against ticks and fleas, killing them on contact. The collar slowly releases low concentrations of both active ingredients, spreading from head to toe, to the tail, over a cat’s coat and skin.

Pros

Place the collar around your pet’s neck, adjust it to a comfortable fit and then do nothing else!

Highly recommended by vets, the Seresto collar makes it easy to kill, repel and prevent flea and tick infections. It uses a patented sustained release technology to provide a long-term solution to fighting the pests that can make a cat’s life miserable.

  • Long lasting protection: This flea collar for cats is one of the most reliable and trusted products cat owners turn to for removing fleas and ticks. Its ability to provide coverage for 8 months long is far beyond anything close to what another brand or model can offer.
  • Effectively handles ticks and fleas: Imidacloprid and flumethrin are the active ingredients used in this cat flea treatment collar to drive fleas and ticks away. Both are excellent repellants, kill fleas in all stages of their lives and fleas don’t have to bite in order for it to work.
  • Great stretch capacity: When using collars, it’s important that they are breakable or stretchable to prevent choking if a cat gets tangled. It is designed with a fantastic two-way opening mechanism. First it opens upon force and then tears off if cats make a critical angle in it.
  • Hassle free and easy to use: Place the collar around your pet’s neck, adjust it to a comfortable fit and then do nothing else! No vials, messy blobs of fur waiting to dry or drops to fuss with. This collar is an easy way to get rid of fleas on cats.
  • Lightweight and comfortable: The material of the collar does not irritate a cat’s neck and most cats get used to its light weight quickly. It is non-greasy, doesn’t emit an unpleasant odor like other collars and even has reflective clips to see cats in the dark.
  • Safe for pets: The active ingredients in this collar have been selected carefully. When used together, they make other ingredients stronger which is why only small doses are needed to effectively remove fleas and ticks and a reason it is so safe, even for use as a kitten flea collar.

Cons

Often listed as the best flea prevention for cats, this Bayer Seresto collar offers a hassle-free solution for cat owners who are tired of reapplication, messiness or products that don’t work. There’s little that it gets wrong, but here are a few shortcomings to look out for.

  • Can cause allergic reactions: Your cat may be allergic to the active ingredients or the collar material. There’s an initial white powder that can causes rashes, especially on kittens. Monitor your cat closely for hair loss, diarrhea, watery eyes and other signs of skin irritation.
  • Adjusting the collar is tricky: Once the collar is around a cat’s neck, it should be adjusted, but it takes some patience. The collar can be loosened but it takes some work. You may have to pull relatively hard and some of the pins may break in the process.
  • Sleeping habits may have to change: When wearing the collar, it is not recommended that you let your kitty sleep with you or your children. If they are used to sleeping on your bed this could be a problem or you can simply switch their collar nightly.

Buying Guide

Oral Options

Some of the most common options available for flea control are oral options, where your cat takes a pill and it protects their entire body. Fleas may still come and bite your cat, but they will die instantly and won’t have the chance to spread.

The best oral flea treatment for cats is going to be something that’s easy for the cat to ingest, whether it’s wrapped in a pill treat or crushed into their food.

Topical Options

As you look at options for topical flea cat products, you’ll often see them referred to as “spot on” treatments. These are some of the most inexpensive options, but they don’t always cover the cat’s entire body.

Usually, you just apply it to the skin (the back of the neck is best, because they can’t reach it) once a month or more if they have had flea issues in the past. They deter fleas from even trying to get on your pet and, if they do, they die instantly.

What Does it Kill?

Different flea treatments are going to do different things, but you want something that takes care of fleas at every stage of their life.

Look at the label to see what the product claims to kill. You’re looking for words like eggs, larvae, adults, pupa, or “entire lifecycle”. That way, your furry friend is going to have the protection that they need, whether it’s from a bite from an adult flea or eggs that get laid on the cat.

All-in-One

Since cats can be finicky, you want to be able to give them as few treatments or pills as possible. That’s why it’s usually best to find products that are “all in one” – for fleas, ticks, and/or heartworm.

Nowadays, most oral treatments have preventatives for all three of these pests. Spot-on treatments usually cover both fleas and ticks, so you would just need to get a supplement for heartworm prevention from your vet.

How Often Do You Apply It?

Oral preventatives usually last longer than spot-on options. Oral preventatives usually come in 3, 6, or 12 month cycles, so your cat is not going to have to take them very often. It all depends on the pill and its makeup.

Spot-on treatments usually need to be reapplied every month. Usually, cat parents will get into a routine where they’re just doing it on a certain day of the month, every month, and it works well for them.

Kitten Care vs. Cat Treatment

Flea treatment for kittens is very different than for cats. You can’t really use any sort of flea product for kittens until they are at least 8 weeks old (but in some cases, it could be up to 6 months).

So, what are you supposed to do if your very young kitten gets fleas? You usually need to remove the fleas manually, with a flea comb or specialized brush. There are a couple of treatments that are okay for kittens 4 weeks old or older – just make sure that you talk to your vet before you try anything.

Natural Ingredients

Did you know that you can find natural flea treatment for cats? Essential oils are effective ingredients to look for. These can include diluted neem oil, Quassia Bark, Geraniol, anise, and thyme. These help to repel pests of all sorts while also safe on a cat’s fur and skin.

Dish soap, lemon spray, rosemary, and baking soda are additional options that work to a certain extent. The ingredients listed above, however, will be more reliable when it comes to getting fleas off of your cat and preventing them from coming back.

Ease of Use

It’s always nice to have an easy way to get rid of fleas on cats – and many products that are available try to make that a possibility. Both oral and spot-on treatments should be simple to use.

Read the instructions on the box or ask your vet about your options. If you have a cat that can be difficult, they may also have some recommendations as to how you can keep them calm and relaxed while you’re taking care of pest issues.

Dosage Options

As you explore your options for vet recommended flea treatment for cats, you will notice that there are a lot of options on the package regarding dosage.

Be sure that you read these carefully ahead of time. These will be based on age, health, and/or weight, allowing you to understand what sort of dosage that you will want to give to your cat. If the chart doesn’t include your cat’s weight, age, or health, then you want to talk to your vet to see if they have a recommended dosage.

Does it Reduce Risk of Disease?

The majority of flea and tick medications are dual purpose; they are supposed to prevent bugs from getting onto your pet in the first place, and kill any bugs that may already be on the cat.

But aside from causing severe irritation, fleas and ticks also carry diseases like lyme disease, mycoplasma haemofelis, tapeworms, and bartonella henselae (better known as “cat scratch disease”). Look on the label to see if the product mentions anything related to reducing the risk of these diseases.

Residue

For topical solutions, you want to be sure that you don’t leave any residue. Any sort of residue is going to annoy your cat and will make it more likely that they try to get it off, thus ingesting it when they shouldn’t be. Flea powder for cats is especially susceptible to leaving residue.

You can always test it out to see if it leaves a film or something sticky on your skin after applying it. Also, look at the label to see if the product contains lufenuron or nitenpyram. These are known for not leaving any sort of residue on the fur.

Suitability

The best flea prevention for cats may not always be the most effective at ridding a cat of fleas. Some products, such as those with rotenone, work well to repel adult pests but won’t necessarily affect eggs or those in the earlier stages of life.

If you’ve already noticed fleas, it’s likely that there are two or more generations in the larva or pupa stage hanging out in your cat’s fur. That means you need a product that will actually kill them, not just a preventative treatment.

Dips and Shampoos

If your cat has already been infested, then you may be looking for dips and shampoos that can help to get rid of the fleas that they are currently having issues with.

When you look for dips and shampoos, try to find something that is meant for cats with sensitive skin. They should have natural ingredients that will kill eggs, larva, and adults. Find something that has a pleasant smell and that doesn’t leave residue after it’s rinsed off.

Brand Reputation

You want to be sure that you take a look at the brand that is offering the flea treatment. This is a time where you don’t want to go with a generic brand – pay a little extra in order to get it from a name that you recognize.

People who have cats are always willing to share their stories with brands that they like or dislike for one reason or another. Search around the web to see which brands have the best reputation and you’ll be on your way.

EPA or FDA Approved

Lastly, when you’re searching for this sort of product, you want to be sure that you find something that has been approved by the Environmental Protection Agency and/or the US Food and Drug Administration.

These have been tested thoroughly by the named organization and have been found to be safe and effective for your furry friend’s needs. Look for it on the label of the best cat flea treatment on the market – it’s usually pretty clearly marked.

Frequently Asked Questions

Can I use flea collars?

Are flea collars safe for cats? Yes. These collars are designed in a way that allows for prevention of fleas and ticks. They usually have some sort of chemical that prevents fleas and ticks from even getting onto your cat in the first place.

That being said, if your cat doesn’t like wearing a collar or they have a knack for exploring, you want to be careful with collars. They could get caught on something, causing your cat distress or injury.

Can I use dog flea treatment for my cat?

Absolutely not! Cats and dogs have different biology and cats are sensitive to some of the chemicals that you will find in the treatment. There have been known cases of cats dying because they used a dog flea treatment instead of one formulated for cats.

Especially problematic is the chemical permethrin. This is an insecticide that is safe for most animals, but cats are very sensitive to it, and cats can end up with permethrin poisoning if they use a dog’s flea treatment.

How effective are sprays?

There are a variety of sprays available for flea treatment, but they usually aren’t for prevention. They will kill any adult fleas and ticks upon contact, and some of them will take care of eggs.

Sprays aren’t necessarily the safest flea treatment for cats, because of the ingredients and because they may end up licking some of it off when grooming. You’re usually better off with oral and spot-on treatments.

Can a cat be allergic to flea treatment?

Yes, they can. Sometimes, the treatment may have ingredients that your cat is sensitive to or allergic to, so you want to keep an eye on them after you go through with a treatment. Always read the ingredients before applying anything to your cat, as well – it could prevent a lot of problems.

Allergic reactions to flea treatment can include itching, congestion, hives, salivating, vomiting, diarrhea, and strange flicking motions in the paw or ears.

Are there other preventative steps I can take?

Absolutely! If you’re trying to prevent your cat from getting fleas, be sure that you are consistently grooming them. Whether that’s with a flea comb that is designed to get rid of any bugs in their fur, or just their ordinary brush, it can help to remove adult fleas before they bite or lay eggs.

If your cat goes outdoors, you may also want to consider natural yard treatments that keep fleas and ticks at bay. These treatments are generally safe for pets, but be sure to talk to your landscaping professional so they know to use pet-safe options.
