Best flea treatments for cats in 2021 Review

An overzealously itching and scratching by a cat can leave a pet owner with bad feelings. Ignoring flea on your cats can be an unwise decision for the entire family because a single flea on your cat can result in an outbreak in your home.

If you want to protect your pet and yourself from fleas, the first and most effective step is prevention. This can be achieved by improving your hygiene, regular housekeeping, and preventing your pet from going out. Also, preventing other pets from associating with your pet and cautioning all family members from carrying and playing with the pet is a positive step in the right direction. However, these preventive measures are strict and often difficult to adhere to.

How most cats got their fleas?

Many pet owners often ask these, especially when their pets are indoor pets. Itching isn’t the first sign that indicates the presence of a flea because some flea might be at the egg or larva stage, and you would not be aware. The exact way to find out is by checking the cat’s body. You can do this by combing through the cat’s fur and whipping with damp white clothes. If you find a red-colored streak on the damp clothes, this is an indication that your cats have fleas.

Naturally, cats are known to care for their personal hygiene. For this reason, it is challenging to spot fleas on them. And the only way to see if they do have fleas is the presence of flea dirt, which is a digested blood eaten by the fleas. Fleas aren’t something you should ignore; instead, it requires urgent attention.

Besides making your pet uncomfortable, fleas can cause your cat to develop anemia due to blood loss. This is very common among smaller cats. Also, in the process of cats trying to remove the fleas themselves, they can mistakenly ingest the fleas, which can give them tapeworm.

Life cycle of cat flea

Understanding a flea life cycle can help you eliminate them properly because some treatment only kills adults’ fleas and not the egg. To permanently eliminate a flea or stop its outbreak in your home, you must eliminate all the flea life stages; else, the eggs will metamorphose into an adult egg.

Surprisingly, adult fleas are just a handful of the flea population, and they represent as little as 5 percent of the flea population. A female flea lays an average of 50 eggs per day, which is why they are quick to cause an outbreak and infect humans.

When your cats play on the furniture, they drop some of the eggs on the furniture. These eggs hatch into larvae which create cocoons and emerge as an adult. This process takes about two years, so this means if you let your cat go untreated for more than a year, you should be expecting an outbreak.

When treating your cat for fleas, endeavor to treat your home, paying particular attention to your bedding, furniture, curtains, carpets, yard areas, and the cat’s play area.

How to choose the safest flea cats

Before purchasing any flea, treatments there are factors you should take note. Any mistake with flea treatment can cost you your pets life so, to avoid such issues, take note the following:

  • Cats’ lifestyle: some cats are outdoor cats while others are indoors. Both are susceptible to fleas, but outdoor cats are more vulnerable because of their exposure.
  • Cat’s age: some flea treatments are not suitable for older cats, so if you remember to mention your cat’s age to your vet to avoid mistakes.
  • Cats Health history: is the cat on supplements or any other drugs? This information will influence the type of treatment that would be suitable for the cat.
  • Cat’s breed: this is their unique identity; their DNA decides it. Don’t forget to mention this to your vet.
  • Cats residential area: if you live in a rural area with so many grasses and trees, then it’s easier for your cat to get re-infected. In this case, a prolonged treatment would be recommended. Also, there some areas that the fleas have shown resistance to certain flea treatment. So don’t forget to mention it to your vet.

For general note, never use a flea treatment meant for dogs for cats except it is written for dogs and cats. Also, follow instructions because some formulations can kill your cat. Cats’ treatments are administered based on their age and weight, and your vets can provide you with this information.

Different kinds of flea treatment

There are different kinds of flea treatment for cats; they include collars, sprays, oral medication, and topical solutions. These same treatment categories are also available for dogs.

There are also homemade flea treatments, and most persons that want to eradicate fleas on a budget opt for it. Some go the extra mile to use essential oils without seeking the advice of their veterinarian. In some cases, these oils would treat the fleas; however, some essential oil has proven to be dangerous and fatal on cats. Examples of essential oils you should avoid include cedar oil, peppermint oil, lavender, tea tree oil, and permethrin.

Always stick to recommended dosage when applying flea treatment because overdose might cause further health issues while under-dose may not be effective. Dosages are calculated using the cat’s age and weight.

If your cats have sensitive skin, the best treatment to adopt are natural powder, flea collars, and cat flea pills. The pills are taken orally and daily, while the collars are worn and easy to apply. Natural cat powders rarely have side effects, although they take time.

A general rule is to apply the treatment to a small portion of the cat’s fur and observe closely for any reaction because some well-known ingredients have caused a reaction at one point or the other, also, for your home cleaning endeavor to use a vacuum cleaner and wash all towels and mats using a high heat washing machine.

How do you get rid of fleas on cats that hate water?

Batting your kitty can help them get rid of fleas. However, some cats are afraid of water and would do anything to avoid taking its bath. Pet owners have found a way around this, and I am going to share it with you.

The strategy is to go slowly and calmly. Any attempt to force your cat will scare it more, so stay calm and speak in a reassuring tone. Cats tend to pick up the same energy as their caregiver, so if you want your cat calm, you also must be calm.

Avoid using cold water instead; use warm water and pour it slowly so the cats can get acclimated to the water. Use recommended shampoo and brush the cat’s fur gently. Also, make sure everything you need is ready and easily accessible; that way, you won’t have to leave the cat unattended, leading to the cat catching a cold.

Among the recommended cat’s flea shampoo are Adam’s ticks and flea shampoo, d-limonene tick, flea shampoo, and other bar soaps.

How do you make homemade flea spray for cats?

Are you trying to get rid of your cats’ fleas, and you want to do so on a budget, or are you not just comfortable with the chemical-made flea treatments? Well, I got you covered?

Fleas are known to hate the taste and smell of vinegar; you can use this information to your advantage by using the same vinegar to wipe them off your cat and surrounding. Start by adding an amount of vinegar to all your household cleaning water, and also prepare a vinegar spray.

The blend you would adopt depends on the degree of the infestation; you can make your vinegar spray with a ratio of 1:1. However, you can increase the concentration if the result is slow. This works by forcing the fleas to exit your cats’ body and all their hideout which allow you to kill them physically. Some might even die as a result of suffocation.

What can I put on my skin to keep fleas off of me?

The fact that you own a pet, whether it’s a dog or a cat, already exposes you to flea bites. To keep this tiny creature away from your skin, you need to wear thick and full clothing always; however, some fleas can find ways of penetrating light clothing. Due to this fact, it will be more beneficial to apply safe flea repellant on your skin.

There are several flea repellants in the stores, but the best that has proven to work against fleas is those containing DEET and permethrin. Use every 12 hours and avoid always exposing your bare skin when attending to your cats or dogs.

Does vinegar kill fleas on cats?

Vinegar does not kill fleas; instead, it makes them uncomfortable. If you apply vinegar on your cat’s skin, the fleas will start to crawl out of their skin, making it possible for you to kill them.

When using vinegar, always mix with water in a ratio of 2:1. That’s is one portion of water to two portions of vinegar. Also, be aware that if the fleas have lay eggs before using the vinegar mixture, these eggs won’t crawl out, so in the end, you will have to keep repeating the same cycle.

Is Frontline Plus for cats any good?

Frontline plus treatment for cats is known to produce fast an excellent result when it was first made. However, due to the recent comments on the products, it seems most users are complaining about a change or modification of one of its ingredients. The complaints are often about skin incompatibility and that fleas are showing resistance to the treatments. So, I would say if you are treating your cat for fleas that have shown resistance to other products, then frontline isn’t a good option, but otherwise, you can give it a try.


Flea is a common nightmare for pet owners; this tiny creature makes cats uncomfortable and sick and goes further to affect pet owners. To eradicate these uninvited guest pet owners must use a suitable flea treatment. That is a treatment suitable for their cat’s age and weight.
