The 10 Best Flea Treatments for Cats
1. Bravecto Topical Solution for Cats — Best Overall
| Form | Topical |
| Quantity | 1 dose |
| Active Ingredient | 250 mg of Fluralaner |
| Length of Efficacy | Up to 12 weeks |

Bracevto can also kill flea eggs and larvae to prevent and treat full infestations. As with any medication, side effects are possible and should be discussed with the veterinarian. Bravecto will not prevent any other parasites outside of fleas and ticks and can be a bit on the expensive side.

It is safe for use in kittens over 8 weeks of age and can be used on pregnant and nursing cats.
This topical solution can be a bit messy and hard to administer, so following instructions is important. Frontline Plus cannot treat any additional parasites and may not always last the full month in terms of efficacy.
A lot of over-the-counter flea medicines are becoming less effective against fleas with time, as they learn to adapt to the widely used medication. Your veterinarian will be able to give you the best advice on non-prescription options in your area.

This is a fast-acting pill that gets the job done within 30 minutes by killing adult fleas. Unfortunately, Capstar is only short-term relief and only lasts 24 to 48 hours. There are six pills in the box that can be given consecutively but will need to be followed up with a longer-term treatment option.

| Quantity | 6 single doses |
| Active Ingredient | 80 mg of Imidacloprid (10%), 8 mg of Moxidectin (1%) |
| Length of Efficacy | 1 month |

Advantage Multi comes in two different weight ranges for cats, and since this is prescription only, your veterinarian will ensure you are given the proper medication for your cat’s weight. Unfortunately, this topical solution cannot kill flea eggs, larvae, or ticks.
It is recommended by the manufacturer that any pets that could lick off the solution will need to be separated from the affected cat after it’s administered, and small children should be restricted from contact with the cat for at least 30 minutes after the application.

The formula is designed to be waterproof and uses imidacloprid and pyriproxyfen to do the job. This is designed for use in cats that are 8 weeks and older and comes in two different weight range options.
The downside to Advantage II is that it does not always last the full 4 weeks, and some users reported seeing fleas return after approximately 2 weeks. As a topical solution, it is naturally messier to administer, and since it is so readily available, there have been reports that fleas have adapted and become more resistant to the formula.
Buyer’s Guide: Selecting the Best Flea Treatment for Cats
How to Check For Fleas
Cats will typically show some tell-tale signs that fleas are present and causing them irritation:
To confirm that your cat is infested with fleas, you can check them by using a flea comb, brush, or your fingers to search their skin and coat. Run the flea comb, brush, or your fingers along your cat’s back and underbelly. You may notice either the fleas themselves or small black specks, known as flea dirt.
Types of Flea Treatments and Preventions
Efficacy Issues in Products
It is important to keep in mind that efficacy issues can occur when attempting to treat a flea infestation. Killing the adult fleas is easy, but eliminating the larvae and eggs and breaking the life cycle can be challenging.
Fleas can be resistant to some more widely used products, so it is not unusual to run into a product that simply does not work for your cat. Other times, you may notice a product does not work for the length of time advertised. For example, a once-per-month medication may only keep the fleas away for 2 weeks.
It is very important to discuss flea treatment and prevention directly with your cat’s veterinarian so they can give you the best option in tackling this pesky problem.
Eliminating an Infestation
To eliminate a flea infestation, your cat needs to be treated, along with any other animals in the home that can fall victim to fleas, such as other cats and dogs. You will also need to treat your home, which can be the most difficult part of the process.
Flea eggs can hide in the carpets, furniture, and all over the house. When the adult fleas are killed off, their eggs are still able to hatch, and the issue begins all over again. You need to eliminate the entire lifecycle of this parasite for successful elimination and a flea-free home.
It can take up to 3 months to fully rid a home of an infestation, and in some cases, you may have to bring in a professional to take care of the job. More than one treatment of the home may be necessary.
Speak to your veterinarian, and they will be able to help guide you through the process and ensure that your pets are covered on the treatment end.
Possible Side Effects
Treating an animal for fleas involves chemicals and side effects are possible. While these treatments are heavily studied before being released for use in our domesticated pets, reactions can vary from individual to individual.
Ensure that other animals in the household are prevented from licking off any topical flea solution on another, as this can be dangerous. Make sure to read any labels on any treatments being done in the home to ensure that all members of the household, both human and animal will be safe during the process.
Be sure to discuss any possible side effects of the flea mediation with your veterinarian. You will need to ensure that the medication is well-tolerated and keep an eye out for any signs of toxicity.
Conclusion
Among these reviews, Bravecto Topical Solution is a great overall choice, though it does require a prescription, and it is for use in cats 6 months or older. It gets the job done well and kills fleas, eggs, larvae, and ticks with an efficacy of up to 12 weeks.
Frontline Plus for Cats is a great choice if you are looking to get good value at a low price. It’s available without a prescription and is easy to obtain. Revolution Plus is a great choice for a topical solution that is effective against fleas, ticks, heartworms, ear mites, roundworms, and hookworms. It dries quickly and is easy to apply.
We hope that while working with your vet, you can find the right flea treatment for your cat!
