Fleas are not just pests, they can prove to be a health hazard. A really bad flea infestation can damage the cat’s skin, make it allergic, or make the cat anemic due to siphoning of blood. Fleas are not as dangerous as ticks in this regards, but they do host other parasites and can release them in the cat’s body.
Talking of flea control, prevention is obviously the best way out but each product works differently. You would need to spare a lot of time to browse through such a large variety of products and make a decision. We have tried to make your job easier by reviewing 10 cat flea treatments and backing them up with a buyers’ guide.
Best Flea Treatment for Cats: Bayer Advantage II
According to our experts, Bayer Advantage II Flea Prevention is the best cat flea treatment as it offers quick and lasting freedom to your kitty from fleas and ticks. The topical formula gets rid of fleas in all life stages. Safe, effective and easy to administer, Bayer Advantage II is popular among many cat-parents and vets.
How to get rid of fleas on cats?
Your first step would be to get rid of as many fleas as possible by using a flea comb and by bathing the cat. Using a flea comb, comb meticulously all over your cat’s body. Keep a jar/bowl of diluted bleach nearby and when you collect fleas on the comb, shake them into the jar to kill them quickly. A good bath afterward can also help to drown the remaining fleas.
Several factors such as effectiveness, safety, cost, side-effects, and formulation should be considered before deciding how to go about treating your kitty for fleas. Effective flea treatment products will contain ingredients to kill adult fleas before they lay eggs or something called an insect growth regulator that will sterilize flea eggs and prohibit immature fleas from growing up and reproducing.
Treatments can be classified into two broad categories: topical flea treatments and oral flea medicine for cats.
Topical flea treatments include spot-ons, sprays, dips, shampoos, and cat flea collars. Many oral flea medicines are available exclusively on prescription, but there are many others that can be purchased over the counter.
While taking steps to remove the pests from your cat is important, equally important is to take adequate measures to wipe them out from the environment (your home). Vacuum your carpet and sweep your floor to remove flea eggs, larvae and pupae.
Bear in mind that 95% of the flea’s lifecycle is spent off your pet. Ensure that you empty or throw away the vacuum cleaner’s bag every time you use it. Treat all cats and dogs. Wash all bedding in hot water. You can also hire a professional to exterminate the pests from your home and the yard.

Our Buyers’ Guide of Cat Flea Treatments
Product reviews are often the best way out to understand a particular product before actually buying. However, product reviews themselves do not address the question of selection on their own. Buyers’ guide will help in understanding different categories of cat flea treatments, and the factors that should influence your decision of selecting a treatment. We have also tried to answer a few FAQs at the end.
Types of Cat Flea Treatments
There are several factors that must be considered before beginning to shop for flea treatment for your pet feline. The most effective products for checking fleas will contain something that will kill adult fleas before they start laying eggs. Alternatively, they also may contain an ingredient that will sterilize flea eggs and prevent the immature fleas from growing and reproducing.
1. Topical Cat Flea Treatments
Topical Cat Flea Treatments are meant to be directly on the cat’s body o treat or prevent fleas. Here are the different types of topical flea treatment available for cats:
- Flea Drops (Spot-ons)
Spot-on treatments require a small amount of a liquid to be rubbed all over your cat once every month. Though manufacturers claim it is waterproof, frequent bathing may reduce their efficacy. These products can also get groomed off, so it is best not to pet your kitty till the liquid dries off after being applied.
- Sprays, Dips & Shampoos
These were once considered to be major parts of flea-check programs. However, dips, sprays, and cat flea shampoos are only effective at killing fleas on the cat at the time of application. They can do little to kill the freshly-hatched fleas that may get introduced through the environment after the treatment. There are a huge number of products available on the market but you have to ensure that the product you are using is safe.
- Cat Flea Collars
Many cat parents have been attracted to cat flea collars because they are easy to use and have no side-effects. Old-style flea collars are not very effective in areas of your cat’s body that are farthest from the collar. Though effective, some newer products are expensive.
2. Oral Flea Medicine for Cats
While many oral flea medicines for cats are available over the counter, many are also strictly available only on prescription. Oral flea medicines have two distinct advantages; No chemical residue is left behind post-use and Their effect is felt equally all over the cat’s body
3. Flea Combs
Just as the name suggests, the flea comb is a grooming device for your pet’s fur. Unlike regular combs, the teeth of a flea comb are more closely spaced enabling it to physically weed out fleas, flea eggs, and flea dirt from the fur.
4. Tick Removal Tools
Tick removal tools are designed to weed out the tick by pulling or twisting and ensures that the tick is safely removed without getting crushed or leaving its mouth part inside the skin, according to companies that sell the tools. There are several published studies that show these tools can indeed remove ticks effectively, even ones that are as small in size as a poppy seed. Scientists though do not believe these tools can do a better job of removing ticks than fine-tipped tweezers, which they believe to be the gold standard.
How to choose the best Cat Flea Treatment for Cats?
All cat flea treatments use insecticides to eradicate fleas on your cat. Do not be scared because it is all safe. All the insecticides used in flea treatments have a certification from the Environmental Protection Agency (EPA) before being allowed on the market. If correctly administered, there is no chance you or your kitty could ever come to any harm.
Avoid these ingredients
However, there are side-effects of cat flea treatments if not administered properly. Also, these products are meant for the home and can come in contact with kids and pets. Hence, it is important to be cautious. According to our experts, the following 4 ingredients should be avoided under all circumstances:
Researchers have proved that Selamectin leaves a high amount of residue after coming in contact with it. If you are going to apply it once or twice every month to your pet, this ingredient has the potential to harm you because you are going to come in frequent contact with it.
As per an expert agency, human beings with exposure to pyrethroids can feel numbness, itching, burning, stinging or tingling.
Cats do not have the ability to metabolize pyrethrins and pyrethroids. Though they are not necessarily harmful, any medicine that uses these ingredients risks overexposing your cat should it come in contact with the same chemicals anywhere else. Pyrethrins are part of many outdoor pesticides, foggers, sprays, and pet shampoos. Pyrethrin toxicity can cause shaking, tremors, seizure, asphyxiation, hypothermia, and vomiting.
According to the EPA, human beings overexposed to Tetrachlorvinphos can suffer side-effects such as nausea, confusion, dizziness or even paralysis and death in extreme cases.
Easy to find and use
There are a number of different forms of cat flea treatments, including liquid spot-on treatments, oral medications, collars, shampoos, and sprays. Spot-ons and oral medicines are the focus of this post.
Why did my cat get fleas?
Cats can catch fleas at kennels, groomers and outside. Exclusively indoor cats never get infested, but cats that are free to go in and out of the house are very likely to get them. There are many different species of fleas but cat fleas (Ctenocephalides felis) can jump 12 inches high onto an unsuspecting host, feed and then lay their eggs in its fur. The eggs fall off the fur onto the furniture, carpet, or any place where your kitty spends time. The eggs then transform into larvae, pupae and finally into adults, starting the lifecycle once again.
What is the most effective and fast-acting flea treatment for cats?
Oral treatments are fast acting because the medications release insecticides straight into the cat’s bloodstream so that when the flea bites, it gets poisoned and dies instantly. They are so quick that they can rid your pet of the pests within an hour, but they will not be able to protect against future infestations in the way a spot-on treatment would.
Which flea treatment is safest for cats?
Cats are very sensitive to pyrethroids, a very common artificial ingredient used in flea and tick treatments. These chemicals are related to pyrethrins, which are natural products derived from the flower of the chrysanthemum plant. Cats do not have the ability to metabolize pyrethrins and pyrethroids.
If you use a treatment with these ingredients, then there is a risk of overexposing your cat to these chemicals that are also an important part of many outdoor pesticides, foggers, sprays, and pet shampoos. Pyrethrin overexposure can cause side-effects such as shaking, tremors, seizure, asphyxiation, hypothermia, and vomiting.
Is there any harmful effect of flea treatment on cats?
Spot-on flea and tick treatments are very popular among cat parents. They are fast acting, easy to administer and considered to be “safe” for most cats. These spot treatments release insecticides over a long period of time. They do rid your kitty of the infestation, but she is also absorbing the chemicals, which can cause harmful side-effects such as seizures, stumbling, hyperthermia (high body temperature) or even result in death.
How often should I use the flea treatment for Cats?
Most people think they don’t have to bother once the weather gets colder, but flea treatments have to be undertaken all round the year to get rid of the nasty little pests. De-flea even when it is cold because when you turn on the central heating, the eggs will hatch and you will not be able to put an end to their lifecycle.
Fleas are parasites that pose a health hazard if left untreated on your kitty. Not all flea treatments work in the same way. It is important to understand the advantages and drawbacks of each before deciding which product to buy. We sincerely hope that this post will enlighten you on the different products and help make an informed decision.
