It’s available in three sizes — 12- or 24-ounce or 1-gallon bottles — to support multi-cat or multi-pet households and can be diluted or used at full strength.

The recipe contains aloe, coconut extract, lanolin, and oatmeal so it doesn’t irritate cats with sensitive skin, and it moisturizes their fur to remove dirt and dandruff.

Although the Adams Plus is suitable for both cats and dogs, it shouldn’t be used on kittens younger than 12 weeks of age. To help this formula work the most effectively, it’s recommended to partner it with other flea prevention measures to subdue infestations around the home and garden.

Formulated using ingredients recommended by veterinarians, the Veterinary Formula Clinical Care Flea & Tick Shampoo protects your cat against flea infestations for up to 14 weeks.

With a fresh, clean scent to keep your feline smelling nice for longer, the Veterinary Formula contains aloe and lanolin to avoid aggravating sensitive skin.

For maximum effectiveness, this shampoo should be left on your cat’s fur for 5–10 minutes before rinsing, which might be difficult if your cat doesn’t like baths. This option is also unsuitable for use on kittens younger than 12 weeks.

The Sergeant’s Gold Flea & Tick Cat Shampoo protects your cat from fleas for up to 30 days and is effective on eggs, larvae, and adult fleas. Along with pyrethrins that kill fleas on contact, the recipe for Sergeant’s Gold contains pyriproxyfen to stop the flea reproduction cycle, in order to combat infestations before they start.

To keep your outdoorsy, dust-loving feline smelling clean for longer, Sergeant’s Gold also includes a spring freesia fragrance.

Only available in 12-ounce bottles, this option is more expensive than some others and doesn’t contain ingredients to soothe sensitive skin. It’s also unsuitable for kittens below 12 weeks old.

Our best flea shampoo for kittens is the NaturVet Herbal Flea Dog & Cat Shampoo. With its herbal recipe, it is gentle on sensitive skin and doesn’t contain chemicals that could potentially harm young kittens. The formula contains a mixture of rosemary, thyme, cedarwood, and geranium to repel fleas and protect your feline from infestations. Along with preventing fleas, NaturVet also keeps your cat’s coat shiny and sleek.

Since NaturVet doesn’t contain chemical pesticides, it might not work as fast as some other options. It also needs to be left on your cat for 10 minutes before rinsing, which may be difficult for kittens that get bored and uncomfortable easily.

Like many other treatments, this shampoo needs to stand for 5 minutes before rinsing.

Buyer’s Guide: Selecting the Best Cat Flea Shampoo

What Are Fleas?

A flea is a brown, wingless insect ranging between the size of a pinhead and ⅛ of an inch long. They have thin, flattened bodies, a tubular snout for sucking blood, and powerful legs that enable them to jump great distances. A flea can jump as far as 7 feet! This makes it easy for them to pass from animal to animal.

Combined with the miserable itching that they cause your cat by sucking their blood, fleas carry disease and can cause health problems for your cat and you.

Fleas can carry tapeworm larvae. If your cat accidentally swallows a tapeworm-carrying flea while grooming, the larvae will develop inside your cat and infect them.

Flea allergy dermatitis can also develop. Flea bites may trigger an immune response in your cat and cause an allergic reaction, leading to even more itchiness and discomfort for them.

If the flea infestation is severe enough, it can lead to anemia from the blood loss, and this can be life-threatening for your cat. Anemia is especially dangerous for small kittens.

What to Look For When Choosing a Cat Flea Shampoo

Now that you know more about cat flea shampoos, there are a few things to keep in mind when choosing the best one for your feline friend. There are so many options available, so getting one that works effectively will make all the difference for your cat. Let’s see how to pick the best cat flea shampoo for your cat.

Make Sure It’s Safe for Cats

The first thing to do is make sure the shampoo that you choose is formulated for cats. Flea shampoo for dogs may not be as effective and can even be harmful in some cases. Cats react differently than dogs to flea products. Giving your cat something intended for a dog could have severe consequences.

Make Sure It’s Age-Appropriate

If flea shampoo formulas are made for adult cats, they may be too strong for kittens to handle. Flea shampoos are not considered to be safe for kittens under 12 weeks old.

Consider Your Cat’s Skin Type

If your cat has sensitive or dry skin, you may want to choose a natural or organic shampoo. These aren’t made with chemicals and can still kill and control fleas. D-limonene is an active ingredient in natural flea shampoos and is made from the peels of citrus fruits. It is safe for people, dogs, and cats but will kill fleas and ticks.

Organic shampoos use essential oils to repel fleas and ticks. Peppermint, clove, and cedar oils may not eliminate the parasites, but they do make the cat’s body an unappealing place for them to live. These shampoos aren’t harsh on your cat’s skin and can be used as an effective preventative against infestations.

Chemical shampoos contain pyrethrins and pyrethroids. Pyrethrins are mixtures of chemicals derived from chrysanthemum flowers. They kill fleas by attacking their nervous systems. Pyrethroids also kill fleas the same way, but these chemicals are manufactured instead of naturally occurring.

Pyrethrin/Pyrethroid Poisoning

Too many of these chemicals can be toxic to cats, and unfortunately, these poisonings are commonly the result of cat owners trying to control fleas and ticks and accidentally using the wrong amount of a product or a product made for dogs instead of cats.

Always make sure you use the intended amount of shampoo on your cat during a bath. Only bathe your cat as often as the directions suggest.

Pyrethrin poisoning can be life-threatening.

How to Use Flea Shampoos on Cats

Read the instructions on the label before you begin. Cat flea shampoos will work differently depending on their ingredients. Know the proper amount to use and how long to leave it on before rinsing. If you are using any topical flea treatments, pills, or collars on your cat, always ask your veterinarian first if adding the shampoo is safe and if the products will interact with one another.

To Begin

When it comes to flea shampoos, where you start using them is important. Once the cat’s body is partially submerged in water, the fleas will move to the areas that aren’t. The highest point of safety for them is the top of the cat’s head. You may see them scurry up there and start to hide.

This is why starting the lather at the head is important. Don’t give the fleas a chance to escape or hide until the bath is over.

Avoiding the eyes, lather the top of your cat’s head gently. The fleas may start to run down their face, so it’s a good idea to have a flea comb handy. Softly and carefully to avoid eye injuries, comb the fleas that you see out of your cat’s face and into the soapy water.

Fleas hide behind cats’ ears and in any nooks and crannies that they can find. Working down from the head, lather up your cat, including in between their toes and tail base. Don’t forget to thoroughly scrub your cat’s stomach and legs.

Treatment Time

Once your cat is lathered, the shampoo may take a while to work. Leave the lather on your cat for as long as you are directed to by the label. Your cat may not enjoy this part, but they will feel much more comfortable when it’s over. The upside is that if the bath is effective, you won’t have to do it again soon.

Rinse

Any shampoo left on your cat’s skin can irritate it, so be sure to rinse them thoroughly. Take care to ensure that no shampoo runs into your cat’s eyes. A helpful rule of thumb is that when you think that your cat is thoroughly rinsed, rinse them again. Then do it once more.

Why Use a Flea Shampoo?

Flea shampoos are not a permanent or complete cure for flea infestations, but they do help in ways that flea powder, collars, and sprays don’t. They cover the hair and skin, leaving no spot untreated. They can kill fleas in minutes and work for weeks afterward to repel fleas and prevent further occurrences. Some also have ingredients to soothe your cat’s skin and provide nearly instant relief.

How to Tell If Your Cat Has Fleas

Excessive grooming, scratching, and head shaking by your cat can be signs of a flea infestation. If you notice these behavioral changes, check their coats.

Moving their fur apart so you can see down to the skin will enable you to watch for anything running or jumping. Fleas can move and jump quickly. You’ll see them running fast and trying to hide as you search through the fur.

You may also notice hair loss or scabbing on your cat’s skin. These can also be signs that fleas are present.

You can use a flea comb to pull through your cat’s coat and yank out any fleas that are trying to hide. You’ll see them stuck to the comb’s teeth. After each comb-through, douse the comb in a bowl of soapy water to remove the fleas and eliminate them.

Conclusion

The Veterinary Formula Clinical Care Flea & Tick Shampoo, as a budget-friendly option, prevents future infestations for up to 14 weeks and contains aloe and lanolin. It has a pleasant scent while keeping flea infestations away.
