If your cat seems restless and keeps scratching its skin nonstop, it’s probably infested with fleas.

Since fleas lay 40-50 eggs a day for around 50 days, they will invariably infest your other pets, your home, and even your body, turning life into one long itchy nightmare.

While Dawn may eliminate adult fleas, it doesn’t kill the eggs. It also wreaks havoc on your poor cat’s exhausted skin.

Read on for five excellent picks to help you find the best cat flea shampoo for your feline.

What to Look for in a Cat Flea Shampoo

After consulting your vet and mixing crushed flea tablets into your kitty’s food, there are a number of things you should take into consideration when shopping for a cat flea shampoo.

Whatever shampoo you end up choosing, always read the label and research the ingredients before using it on your cat.

Effect on Fleas

If you can, find a shampoo that not only eliminates adult fleas but also kills fleas at their other three stages of life.

Another excellent option to look for is shampoos that also repel fleas for a week after your cat’s bath.

Insect Growth Regulator

Look for a shampoo with insect growth regulators, also known as IGRs.

These work by disrupting the flea life cycle, stopping non-biting larvae from developing into biting adults, eventually killing the larvae.

The good news is that IGRs are practically non-toxic to cats, other pets, and humans. IGRs also have a long-lasting effect: They can keep working up to seven months.

The downside is that they work slowly on biting adult fleas.

This is why they’re usually used in combination with other insecticides that work faster on that particular life stage.

Rinse-Out vs. No-Rinse Shampoo

Most flea shampoos need to be left on your cat for five minutes or longer.

If your furball will never stand for staying wet or getting wet in the first place, you’re better off with a dry no-rinse shampoo.

These types of shampoo foam up with no water added, allowing you to work them into your cat’s fur and maybe even comb through its hair while your kitty is none the wiser.

Moisturizing Ingredients

Your cat’s fur and skin are already in pretty bad shape, having been bled dry by fleas and scratched furiously by your kitty’s claws.

The last thing your cat needs is a harsh shampoo that dries it out even more.

Look for ingredients that help soothe your feline’s flea-ravaged skin without making its fur fall out along with the dead fleas.

Coconut oil, for instance, is a well-known conditioner, capable of soothing itchiness, dryness, and coat health overall.

A naturally occurring preservative, Vitamin E is also brimming with powerful antioxidants.

It helps protect your cat’s delicate skin against the elements, especially with all the scratching leaving it probably broken and bleeding.

Oatmeal works miracles to calm dried-out, itchy skin, with micronized oatmeal proteins preserving the natural moisture content of your cat’s skin.

Famous for its gooey gel, aloe vera is widely used in beauty and skincare products worldwide.

It’s not only rich in amino acids but also chock-full of vitamins A, B, C, and E, helping your cat maintain a healthy, supple coat.

Its Acemannan content protects moisture in healthy skin.


Make sure the shampoo you pick meets the following safety checks.

Cats Less than 12 Weeks Old

Most flea shampoos aren’t safe for use by cats younger than 12 weeks old.

If your kitty is in that age group, look for a shampoo that explicitly states it’s safe for use on kitties that young.

No essential oils

Even though it’s so dangerous it can often be lethal, the essential-oil fad shows no signs of slowing down.

As a vigilant pet parent, you need to make sure there are none in your cat’s shampoo.

Below are just a few essential oils that are toxic to cats, whether ingested or touched:

  • citrus
  • pennyroyal
  • peppermint
  • pine
  • sweet birch
  • tea tree, also known as melaleuca
  • wintergreen
  • ylang ylang


Keep in mind that you won’t be treating the one flea-infested feline: If you have other pets, you need to give them all the same treatment, in addition to treating your entire home.

This means you’ll be doing 2-4 applications a month on all your pets on a regular basis.

If you’re on a tight budget, economy-sized bottles are an ideal choice.


Small in size but absolutely monstrous in their problems, fleas are the bane of every pet parent.

Luckily, our top pick, Vet-Kem Ovitrol Plus Flea and Tick Shampoo for Dogs and Cats, can help you get on top of the problem faster than any other shampoo.

However, remember that shampooing your cat is only part of the battle.

Keep your furball’s bedding clean and treat your home and pets against fleas, and those blood-sucking nuisances will stay out of your cat’s coat — and yours!
