    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.

    Overall, due to the ability to kill the flea lifecycle and the length of efficacy, Bravecto gets our top spot as the best overall flea treatment for cats.

    Pros
    • Kills fleas, eggs, and larvae
    • Kills ticks
    • Efficacy up to 3 months
    Cons
    • Not for use in cats under 6 months of age

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.

    • Safe for kittens 8 weeks or older and pregnant or nursing cats

    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.

    Active Ingredient Flumethrin, 4.5%; Imidacloprid, 10.0%
    Length of Efficacy Up to 8 months

    Re-infesting fleas are typically repelled in a 2-hour window after the initial 24 hours, and ticks will be killed off within 48 hours of initial application. The collars are very easy to use and are adjustable for the perfect fit. Cats must be at least 10 weeks of age to use this collar.

    While Seresto is non-greasy and odorless, children should not come in contact with it. It can be worn alongside your cat’s regular color for up to 8 months of effectiveness. It is water resistant and protects against flea larvae as well.

    Active Ingredient 80 mg of Imidacloprid (10%), 8 mg of Moxidectin (1%)

    Advantage Multi Topical Solution for Cats is a prescription topical solution that kills adult fleas, treats ear mites, roundworms, and hookworms, and can even help prevent heartworms.

    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.

    Active Ingredient Imidacloprid, 9.1%; Pyriproxyfen, 0.46%
    Length of Efficacy Up to 4 weeks

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.

    Buyer’s Guide: Selecting the Best Flea Treatment for Cats

    • Veterinarian Recommendation: Since there are so many flea treatments on the market and most of them involve chemicals, it is important to discuss flea treatment directly with your cat’s veterinarian. They are professionals who are well-versed in treating fleas and will be able to guide you on the best path to keeping your cat and home free of fleas.
    • Cat’s Age: Most flea medications are designed for kittens that are at least 8 weeks of age and with some brands, older than that. You do have to take into consideration the age of the cat you are providing treatment for and ensure that they are getting age-appropriate medication. Very young kittens are typically treated with bathing and flea combs until they are of age to tolerate flea prevention.
    • Cat’s Weight: Before purchasing a flea treatment for your cat, you need to know their exact weight. Flea treatments are designed for different weight ranges, and it is very important to administer the medication for their proper weight range.
    • Cat’s Health: Discuss the current state of your cat’s health with your veterinarian to help you come to the best choice of flea treatment. A licensed veterinarian will be able to recommend the best option for your cat’s overall health. Keep in mind that cats with sensitive skin may not tolerate topical solutions, and it may be best to go for an oral medication.
    • Type of Parasite Protection: Some of the flea treatments on the market can prevent and treat other parasites, such as ticks, roundworms, hookworms, eat mites, and even heartworm. Having extra protection is always a plus, but not all treatments will be effective against additional parasites. Also, make sure to read the product information to see if the product can help kill the flea lifecycle by killing eggs and larvae. Some treatments are only effective against adult fleas and with more severe infestations, you may need something that can handle all life cycles.
    • Preference: You need to consider which option would be the best for you and your household. For instance, flea collars should not be touched by small children, and topical solutions can be messier and have the risk of being licked off by other animals in the household during grooming. Only you know what your household consists of and the habits of the people and animals within the home. Your veterinarian can help you make the best decision for your circumstances.

    How to Check For Fleas

    Cats will typically show some tell-tale signs that fleas are present and causing them irritation:

    • Frequent scratching
    • Hair loss
    • Skin irritation, scabs, lesions
    • Excessive grooming
    • Black specks within the fur and/or on surfaces the cat lays on

    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

    • Topical medication
    • Oral medication
    • Collars
    • Shampoos
    • Powders
    • Sprays
    • Flea dip

    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.
