Flea treatment for cats doesn’t just help your pet get rid of an irritating, nasty parasite but it also helps prevent a myriad of issues fleas can cause to felines. Take a look at the most effective flea treatment on cats on the market and make your pic

Is your kitty scratching like a maniac? In most cases, the reason for this is a flea infestation. Just like dogs, cats can also fall prey to these pesky little parasites. Fleas love nothing more than making a home out of your pet’s coat and a snack of their blood: the bites are not just unpleasant but the saliva fleas release in the process irritates their skin and makes them scratch incessantly. In addition to being highly unpleasant, fleas in cats can cause a lot of trouble. Cats infested with fleas can lose hair and get inflamed skin thanks to flea allergy dermatitis, they can become anemic, or become ill from some of the diseases this parasite transmits such as Bartonellosis, cat scratch fever, or infestation with tapeworms.

To prevent all this hassle and make sure your kitty stays happy and healthy, you need to eradicate fleas from their fur once and for all. Flea treatments for cats come in many forms, from collars to topical products to chewable tablets, and can successfully kill fleas in various life stages, as well as prevent future infestations. Of course, not all types of flea treatments for cats will work for your pet. Some can be given only to certain age groups, others won’t work if your cat is not cooperative, and some require some extra care, e.g. not letting your pet get wet for a certain period of time. This is why you should do the research beforehand- to make sure that the treatment really works for your pet’s individual needs. We’ve rounded up the best flea treatments for cats that the market has to offer so any pet parent can easily find the perfect match for their kitty- in no time.

Best for kittens: Natural Chemistry Flea Shampoo for Cats & Kittens

This mild botanical formula will help get rid of the nasty buggers without irritating your pet’s skin and coat thanks to the key ingredients that naturally eliminate fleas such as clove oil, cedarwood oil, and cinnamon oil.

Best for treating home/yard: Adams Flea and Tick Home Spray

To successfully get rid of fleas once and for all, you’ll have to treat your pet(s) and space they spend time in simultaneously.

This insecticide spray kills a range of critters, including fleas, flea eggs, flea larvae, ticks, bed bugs, cockroaches, and more.

Best natural: mdxconcepts Organic Flea and Tick Control Spray for Cats

Some pet parents prefer going the natural route as the thought of using harsh chemicals on their sensitive pet sounds scary.

By relying on botanicals, this natural flea spray for cats doesn’t just kill and repel fleas at all life stages but does the same for ticks and mosquitos.

How to Know If My Cat Has Fleas?

While it might be tempting to blame fleas for your cat’s every itch, that’s not always the case and it’s important to eliminate any other medical cause for your pet’s scratching. To make sure it’s really fleas that are bothering your cat, look for the following signs, in addition to itchiness and irritation:

  • Movement in the fur
  • Black specks in the fur or in your pet’s sleeping space (flea poop)
  • Excessive grooming
  • Lethargy (in severe infestations)
  • Hair loss and scabbing

Types of Flea Treatment for Cats

Fleas can be eliminated in a number of ways, but not all of them will work as efficiently- what works great for some pet owners doesn’t necessarily have to work for others. Luckily, there are plenty of types of flea treatments for cats, so everyone can find a match for their cat’s needs.

Spot on treatment or “drops”

This topical preventative and treatment comes in a form of liquid and is applied on the back of the neck- and unless your cat is very squirmy, it is not difficult to apply. Depending on the formula and the brand, some of these will last for up to a few weeks, and either kill only adult fleas or fleas in all life stages.


If you’re well-versed in giving your cat medicine, oral flea treatments might just be the easiest method for you. These tablets work from the inside to eliminate the fleas by releasing certain substances in your pet’s bloodstream, which will kill or sterilize fleas the moment they bite your pet. Of course, the substances are just harmful to parasites- not your pet.


Some owners prefer to put a flea-repellent collar on their pet and call it a day. This might work for some situations, but in the case of more serious infestations, it probably won’t do the trick. The main downside to collars is that they are limited to one area of the body and can cause irritation in sensitive cats.


Getting a cat to a bath might be a challenge, but sometimes the effort is worth it. Anti-flea shampoos for cats are often recommended for kittens as they tend to be mild enough not to irritate their gentle system but efficient to eliminate the flea infestation in its starting stages.


Spritzing your kitty a few times to eradicate fleas seems like a good deal for most- if your pet is not afraid of the spray. Alternatively, flea treatment sprays are often meant to be used around the house or the yard to help eliminate fleas in the environment as well, which is an important part of the process.
