1. Merial Frontline Plus Flea and Tick Control — Best Cat Flea Treatment

Frontline Plus for Cats and Kittens (1.5 pounds and over) Flea and Tick Treatment, 6 Doses

This flea medicine for cats from Merial gives you everything you need to protect your cat from all forms of fleas, lice, and ticks.

It is a long-lasting preventative measure that stops pets from getting infected in the first place.

This treatment takes care of not just fleas and ticks, but other pests too. It kills them in any stage of development and prevents future infestations.

This is a ‘spot on’ product that simply involves snapping the top off a vial and emptying the contents onto your cat’s neck. It will get to work straight away and clear any problem up within 12 hours.

Each treatment then provides up to a month of protection. Within the box, you get 6 vials, which is enough to keep you covered for six months.

It is designed for cats of all breeds that are older than 8 weeks, although they offer a range of different types that are suitable for larger animals if that is what you need.

This product is particularly good if you live in an area with increased risk of lice and ticks as well as fleas, but is a solid choice for any pet owner.

As with all topical applications, though, it is important that you try a small amount on your pet’s skin for a day before administering the full dose to make sure they aren’t allergic to any of the ingredients. You should also only purchase the product from reputable sellers to ensure you receive the proper product and not a forgery.

  • Weight: 0.16 ounces

2. Bayer Advantage II Flea Control Treatment

Bayer Animal Health Flea Prevention for Cats Over 9 lbs, 6 Pack, Advantage II

This flea medicine for cats from Bayer includes 6 vials of easy to apply liquid that protects your cat from fleas for at least four weeks.

The dosage is designed for cats that are older than eight weeks and weigh more than 9 pounds, but the company also provides other options for you if your cat is smaller.

It kills fleas no matter what stage of the lifecycle they are in and is designed to continue working even if your cat has gone for a swim, or is washed.

Of the various methods through which flea medication can be administered, drops are my personal favorite because of the ease of use.

It can often be tricky to get your pet to eat a tablet, for example, so the ability to simply squeeze the vial of liquid onto their neck makes the whole process stress free.

This particular formula deals with fleas no matter what stage of life they are in. It protects your cat for four weeks, and with regular use will ensure your cat remains flea free.

If you are looking for an easy to use product that will eliminate the problem of fleas, then this medicine from Bayer is worth a look.

Specs

  • Doses: 6
  • Cat Support: 8 weeks or older and weighing over 9 pounds
  • Treatment Duration: 30 days

3. Capstar Novartis Flea Tablets

Capstar Fast-Acting Oral Flea Treatment for Cats, 6 Doses, 11.4 mg (2-25 lbs)

Capstar flea medicine for cats has been formulated to deal with fleas once your pet has become infested with them.

They can be used on cats and dogs, and promise to kill all the adult fleas within 6 hours of one dose being administered.

This is a slightly different type of product, as it is designed for clearing up an outbreak of fleas, as opposed to providing protection against getting them.

This is an important difference and will affect whether this is the best cat flea medicine for you.

It is aimed at people who want to treat their pets after visiting places that risk exposure to fleas, or who want to treat new animals before introducing them to a flea-free area (such as at a kennel or vets).

One tablet will kill all the adult fleas on the pet within 6 hours to make your cat much more comfortable and happy.

This is a great product for treating the immediate problem but will need to be used in conjunction with a long-term preventative medicine to stop your cat from becoming infected again, particularly if you live in an environment where fleas are a problem.

With having pets around the home you can soon find yourself dealing with a flea infestation. This is just a part of having animals around and can be easily dealt with.

If you are looking for medication to eliminate a problem you have, or suspect you may have, then this product could be exactly what you need.

If it is long-term prevention you are looking for, then this is not the one for you and you should look at the other products in this guide.

Specs

  • Doses: 6
  • Cat Support: 4 weeks or older and 2 pounds or higher
  • Treatment Duration: N/A
  • Weight: 0.64 ounces

The Advecta II flea treatment is one of the best topical flea treatment for cats and kills fleas of all stages, as well as prevents your cat from picking them up in the first place.

The package includes 4 vials of medicine to provide cover for four months.

This flea medicine for cats has been designed to deal with both aspects of flea problems; killing fleas that are already present and preventing any new ones from joining.

It promises to kill all adult fleas, eggs, and larvae within 12 hours of applying the drops, and protect your cat from new infestations for a further 4 weeks.

Fortunately, the product is waterproof too, so it is not washed off at the first sign of activity. It will stay effective after swimming, rainstorms, baths, and shampooing, so as long as you apply it every month you will be safe in the knowledge that your cat is protected.

It is also good that it is fragrance-free, unlike some other products, so your pet is not left with a nasty smell for days after being treated.

This particular version of the medicine provides you with enough to cover a cat that weighs over 9 pounds for four months.

Advecta offers a wide range of solutions though, so no matter if you are looking to protect a cat or dog of any size, they will have a product suitable for you.

If you are looking for a long-term preventative cover that is easy to administer, then this product from Advecta is worth considering.

Cheristin Flea Treatment Topical for Cats is another great flea and tick treatment for cats. This is one of the best flea treatments for cats and it was formulated specifically for cats.

This solution contains a unique ingredient – Spinetoram – that does a great job when it comes to killing and keeping fleas away.

Interestingly, the active ingredient of this solution exhibits the action mechanism of both Fipronil and Imidacloprid.

However, this solution is only effective against fleas; it is not effective against ticks and lice.

The treatment is very easy to apply and it does not emit any odor after application. This means your cat will be cool with it, as it would not cause any irritations.

It becomes very effective 30 minutes after you apply it, and the protection period is 30 days. This means you would not apply the solution for a period of 30 days, as your cat would be fully protected within this period. It kills 98 to 100 percent of fleas within 12 hours upon application.

You can also use it with other cat skin treatments, as it does not react with other chemicals. It is very safe and your cat is not going to have any complications using it.

Cat Flea Medicine Background

Fleas are a painful and potentially dangerous problem that pet owners face, and must be dealt with as soon as possible.

They can cause a wide range of health problems and can be picked up from all of the places that cats like to visit.

It is also vital for the health of you and your family that fleas are kept away as they can be extremely uncomfortable for you to have around too.

Flea medications come in a wide variety of types, and you need to decide exactly what you are looking for before you can decide which one to choose.

You can get ones that simply kill off all fleas that are present, provide your pet with long term protection against new fleas, and ones that protect against more than just fleas if you feel your cat is at risk from ticks and lice too.

Best Flea Treatment For Cats: A Buyer’s Guide

Your Cat’s Weight

One of the first things you need to consider when looking for the best flea medicine for your cat is the weight of your cat.

Flea treatments and medications are formulated for cats under or over a certain weight. Hence, it is important that you pick an option that is ideal for your cat to use.

If your cat is very small, you need to make sure you go for a treatment solution that is ideal for it.

You can get your small cat sick if you use treatments that are designed for larger cats on it. On the other hand, using treatments designed for small cats on larger cats may be less effective.

As such, you need to make sure you choose the right treatment for your cat.

Effectiveness

Nobody wants to invest in something that will not work, and we are sure you do not want that also. When picking a flea and tick treatment for your cat, you want to make sure the solution is very effective at protecting your cat from fleas and ticks.

However, it is very difficult to test the effectiveness when you are purchasing this product online. There are still some ways you can check this, however.

To know how effective the product is, we recommend you read reviews of previous customers.

Method Of Application

Another thing you need to consider is the ease and method of application. The common flea treatment applications methods are spray, topical spot-on, oral tablet, and shampoo.

The best option depends on what works for you and your cat. While shampoos are very effective, bathing some cats is a very difficult task.

On the other hand, spot-on and spray treatments are very easy to apply, but some of them may be waterproof and may have a chance of accidental ingestion.

Oral tables are also pretty easy, but they sometimes do not offer long-term protection. Hence, you need to consider which option works best for you and your cat and stick to it.

Final Thoughts On The Best Flea Treatment For Cats

Fleas can cause a whole range of problems for pets and owners alike, so it must be controlled to ensure a happy, enjoyable life for your cat.

It is an easy problem to deal with that involves medication as well as keeping your cat and the area they live in nice and clean.

For urgent problems, one of the pill-based medications is most suitable, but our choice for the best flea medicine for cats is the Merial Frontline Plus because of its long-acting preventative formula that not only protects your pet from fleas but also protects from lice and ticks.
