Reviews

Frontline Plus for Cats – The Best Buy
 

  • Form Topical
  • 6 single doses are available.
  • Fipronil (9.8%), (S)-methoprene (11.8%) are the active ingredients.
  • Efficacy Duration
  • 1 month maximum

Frontline Plus for Cats is a great option if you want a flea treatment that will give you the most bang for your buck while still treating fleas.

Frontline Plus, which is available without a prescription, is intended to kill fleas, eggs, and larvae. It is safe to use on kittens over the age of 8 weeks and on pregnant and nursing cats.

This topical solution can be messy and difficult to apply, so following the instructions is critical. Frontline Plus cannot treat additional parasites and may not always be effective for the entire month.

Many over-the-counter flea medications are becoming less effective against fleas as they adapt to the widely used medication.

Your veterinarian will be able to provide you with the most up-to-date information on non-prescription options in your area.

Pros

  • There is no prescription required.
  • Fleas, eggs, and larvae are all killed.
  • Kittens 8 weeks and older, as well as pregnant or nursing cats, are not at risk.

Cons

  • The effectiveness does not always last a full month.
  • Sloppy application
  • No other parasites are to be treated.

 

Cat Flea Treatment Capstar Nitpyram – Best for Kittens
 

  • Form Tablet
  • Quantity 6
  • Nitenpyram 11.4mg Active Ingredient
  • Efficacy Duration: 24 to 48 hours

Capstar nitepyram Cat Flea Treatment is the best choice for flea treatment in kittens. Kittens 4 weeks and older can take this small pill. Outside of bathing and flea combing, kittens of any age cannot be treated for fleas.

This is a quick-acting pill that kills adult fleas in less than 30 minutes. Unfortunately, Capstar provides only short-term relief, lasting only 24 to 48 hours. The box contains six pills that can be taken in succession but must be followed by a longer-term treatment option.

Capstar is available without a prescription and is a little pricey for the short-term effects. Only adult fleas are killed by this method, not eggs or larvae.

Pros

  • Fleas are killed within 30 minutes.
  • No prescription is required.
  • Can be used on kittens aged 4 weeks and up.
  • There is no prescription required.

Cons

  • Lasts only 24 to 48 hours
  • It has no effect on eggs or larvae.
  • Expensive for temporary relief

 

Seresto Cat Flea & Tick Collar – Best Flea Collar
 

  • Form Collar
  • Quantity 1 collar
  • Flumethrin (4.5%) and Imidacloprid (10%) are the active ingredients.
  • Efficacy Duration
  • Up to eight months

Seresto Flea and Tick Collar For Cats is a veterinarian-recommended flea collar that can be purchased over the counter.

This collar starts repelling fleas within 24 hours of being placed on your cat. This product works by making contact with the flea and does not require the flea to bite.

After the initial 24 hours, re-infesting fleas are typically repelled in a two-hour window, and ticks are killed within 48 hours of initial application.

The collars are very easy to use and are adjustable for the perfect fit. To use this collar, cats must be at least 10 weeks old. Seresto is non-greasy and odorless, but it should not be used by children.

It can be worn alongside your cat’s natural color for up to 8 months. It is water-resistant and repels flea larvae as well.

The disadvantage of Seresto is that there has been some debate about its safety, and there may be side effects. Before using this collar, consult with your veterinarian.

Pros

  • It repels fleas, larvae, and ticks.
  • Efficacy for up to 8 months
  • Waterproof and adjustable in size
  • It is not necessary for fleas to bite for it to work.
  • There is no prescription required.

Cons

  • Serious side effects are possible.
  • The collar should not be worn by children.
  • It is not recommended for kittens under the age of ten weeks.

 

Cheristin Cat Flea Spot Treatment
 

  • Form Topical
  • 6 single doses are available.
  • Spinetoram 11.2% active ingredient 88.8% other ingredients
  • Efficacy Duration: 1 month

Cheristin Flea Spot Treatment for Cats is a monthly topical solution that kills fleas within 30 minutes of application and kills 98 to 100 percent of fleas within 12 hours.

The non-greasy formula makes it easier to apply than some other topical solutions. This option is intended for cats and kittens 8 weeks of age or older and weighing more than 1.8 pounds.

This flea treatment does not require a prescription, which is convenient. Cheristin does not kill flea eggs, larvae, or other parasites, and its effectiveness may not last for the entire month.

Fleas are adapting to the formula in some areas, so it may not be as effective as a prescription medication.

Pros

  • There is no prescription required.
  • Within 12 hours, it kills 98 to 100 percent of fleas.
  • There is no prescription required.
  • Can be used on cats weighing 1.8 pounds or more.

Cons

  • It has no effect on eggs, larvae, or other parasites.
  • The effectiveness may not last a full month.
  • Some fleas appear to be resistant to ingredients.

 

Advantage II Cat Flea Spot Treatment
 

  • Form Topical
  • Single doses in quantities of 1, 2, 4, or 6
  • Imidacloprid 9.1%, Pyriproxyfen 0.46% are the active ingredients.
  • Efficacy Duration
  • Up to four weeks

Advantage II Flea Spot Treatment for Cats is a topical solution that works for up to 4 weeks. This solution starts working within 12 hours and can kill adult fleas, larvae, and eggs. This aids in the disruption of the flea’s entire lifecycle.

Advantage II is available without a prescription, making it far more accessible, and can be found in pet stores and large department stores.

The formula is intended to be waterproof and employs imidacloprid and pyriproxyfen to accomplish this. This is intended for use in cats aged 8 weeks and up and is available in two weight ranges.

The disadvantage of Advantage II is that it does not always last the full four weeks, and some users have reported seeing fleas return after about two weeks.

It is naturally messier to administer as a topical solution, and because it is so widely available, there have been reports that fleas have adapted and become more resistant to the formula.

Pros

  • Within 12 hours, work begins.
  • Fleas, eggs, and larvae are all killed.
  • There is no prescription required.

Cons

  • Sloppy application
  • It does not always last the full four weeks.
  • Some fleas may be immune to certain ingredients.

 

Catego Flea and Tick Spot Medication
 

Catego‘s most notable feature is its applicator, which is effective against both fleas and ticks. It’s extremely easy to use and allows you to apply the oil exactly where you want it without getting it all over yourself.

Fipronil, Dinotefuran, and Pryiproxyfen are among the active ingredients in the flea-killing formula. This means that if one of the three ingredients does not kill fleas, one of the other two will.

Of course, even if the authorities have approved it, some owners will object to putting that many chemicals on their cat.

There is only one dosage size available, which is intended to treat all cats weighing more than 1.5 pounds. This could be a problem if you have a large breed, such as a Maine Coon, because it will be less effective on them than, say, a Cornish Rex.

Catego appears to have a pleasant flavor, as cats enjoy licking it off one another. You don’t want them to do this, so keep them apart until the oil dries if you have more than one cat.

Pros

  • Simple to use with a handy applicator
  • Three active ingredients ensure long-term efficacy.

Cons

  • Some cat owners may object to using so many chemicals on their pet.
  • There is only one dosage size.
  • Large breeds are less effective.
  • Cats appear to enjoy flavor.

 

Virbac EFFIPRO Cat Flea and Tick Spot Treatment
 

Virbac EFFIPRO, like Frontline Gold, contains only two active ingredients (it lacks S-methoprene). However, because it contains Pyriproxyfen as well as Fipronil, it may be effective if other treatments have failed.

The problem with this formulation is that because Fipronil and S-methoprene work so well together, they are almost always used together. It’s unlikely to be as effective because you’ll be relying primarily on Pyriproxyfen.

EFFIPRO is meant to be a less expensive alternative to the other product, but it isn’t significantly less expensive, so there’s little reason to choose it unless Frontline Gold hasn’t worked for you.

The manufacturer appears to be aware of this, as there are numerous pairing suggestions. While there’s nothing wrong with using multiple flea control methods, it’s far more convenient (and cost-effective) to find a single product that works on its own.

Application is also time-consuming. You must unscrew the cap before puncturing the tube’s seal. This is obviously impossible while holding a squirming cat, but if you puncture it before grabbing the cat, some formula will leak out. It’s a no-win situation.

Virbac EFFIPRO does not have any inherent flaws. On the contrary, you should anticipate seeing results. It’s just difficult to recommend it when more effective alternatives are available in the same price range.

Pros

  • Frontline Gold’s less expensive alternative

Cons

  • It lacks one of the main flea-killing ingredients found in Frontline Gold.
  • Difficult to implement
  • When combined with other flea-killing products, it works best.
  • Not much less expensive than Frontline Gold.

Buyer's Guide: Choosing the Best Cat Flea Treatment

Veterinarian Advice

Because there are so many flea treatments on the market, the majority of which contain chemicals, it is critical to discuss flea treatment with your cat’s veterinarian.

They are professionals who are well-versed in flea treatment and will be able to advise you on the best way to keep your cat and home flea-free.

Cat’s Age

As previously stated, most flea medications are intended for kittens at least 8 weeks old, and in some cases, much older.

You must consider the age of the cat for whom you are providing treatment and ensure that they are receiving age-appropriate medication.

Bathing and flea combing are usually used on very young kittens until they are old enough to tolerate flea prevention.

Weight of Cat

Before purchasing a flea treatment for your cat, you must first determine its exact weight. Flea treatments are designed for different weight ranges, and it is critical that the medication is given to the correct weight range.

Cat’s Health

Talk to your veterinarian about your cat’s current health to help you choose the best flea treatment. A licensed veterinarian can advise you on the best course of action for your cat’s overall health.

Keep in mind that cats with sensitive skin may not tolerate topical solutions and that an oral medication may be preferable.

Type of Parasite Protection

Some flea treatments on the market can also prevent and treat ticks, roundworms, hookworms, eat mites, and even heartworms.

Having additional protection is always beneficial, but not all treatments are effective against additional parasites. Also, read the product information to see if the product can aid in the killing of the flea lifecycle by killing eggs and larvae.

Some treatments are only effective against adult fleas, and for more severe infestations, you may need something that can deal with all stages of the lifecycle.

Preference

You must decide which option is best for you and your family. Flea collars, for example, should not be touched by small children, and topical solutions can be messier and risk being licked off by other animals in the household during grooming.

Only you know what your household is made up of, as well as the habits of the people and animals who live there. Again, your veterinarian can assist you in making the best decision for your specific situation.

What You Should Know

How to Detect Fleas

Cats typically exhibit the following symptoms when fleas are present and causing irritation:

  • Scratching frequently
  • Loss of hair
  • Skin rashes, scabs, and lesions
  • Grooming that is excessive
  • Black specks in the cat’s fur and/or on surfaces it lays on

To confirm that your cat is flea-infested, search their skin and coat with a flea comb, brush, or your fingers.

Flea comb, brush, or your fingers should be used to clean your cat’s back and underbelly. You may notice fleas or small black specks, which are known as flea dirt.

Flea Treatments and Preventative Measures

  • Medication for the Skin
  • Medication Taken Orally
  • Collars
  • Shampoos
  • Powders
  • Sprays
  • Dip for Fleas

Product Efficacy Issues

When attempting to treat a flea infestation, it is important to keep in mind that efficacy issues can arise. Killing adult fleas is simple, but eliminating larvae, eggs, and breaking the life cycle can be difficult.

Fleas can develop resistance to some commonly used products, so it is not uncommon to come across a product that simply does not work for your cat.

Other times, you may notice that a product does not work for the duration stated. A once-a-month medication, for example, may only keep fleas away for two weeks.

It is critical to discuss flea treatment and prevention with your cat’s veterinarian so that they can advise you on the best way to deal with this annoying problem.

Getting Rid of an Infestation

To get rid of a flea infestation, treat not only your cat, but also any other animals in the house that can get fleas, such as other cats and dogs. You will also need to treat your home, which can be the most challenging aspect of the process.

Flea eggs can be found in carpets, furniture, and other areas throughout the home. When the adult fleas are killed, their eggs can still hatch, and the cycle begins again.

For successful elimination and a flea-free home, you must eliminate this parasite throughout its entire lifecycle.

It can take up to three months to completely rid a home of an infestation, and in some cases, you may need to hire a professional to do the job. More than one home treatment may be required.

Speak with your veterinarian; they will be able to guide you through the process and ensure that your pets are covered for treatment.

Potential Side Effects

Chemicals are used to treat an animal for fleas, and side effects are possible. While these treatments are thoroughly researched before being approved for use in our domesticated pets, reactions can vary from person to person.

Make sure that no other animals in the house lick any topical flea solution off another, as this can be dangerous.

Read all labels on any treatments done in the home to ensure that all members of the household, both human and animal, are safe during the process.

Consult your veterinarian about any potential side effects of the flea medication. You must ensure that the medication is well-tolerated and keep an eye out for any signs of toxicity.

Conclusion

Advantage II Cat Flea Spot Treatment is an excellent overall choice; though it does require a prescription and is only for use in cats 6 months and older, it works well and kills fleas, eggs, larvae, and ticks for up to 12 weeks.

Frontline Plus for Cats is an excellent choice if you want to get good value for your money. Frontline Plus is easily accessible and available without a prescription.

Catego Flea and Tick Spot Medication is an excellent topical solution for treating fleas, ticks, heartworms, ear mites, roundworms, and hookworms. It dries quickly and is simple to use.

After all is said and done, we are grateful that, out of the dozens of websites available, you chose BestForPets (bestforpets.org) to read evaluations of the best cat flea treatments.

We really hope that this essay was able to assist you in selecting the best possible item for your pet.
