Best Cat Shampoo for Fleas and Allergies

Fleas and allergies are very burdensome on cats and their owners alike. It is never a pretty sight, so it is best to find the best cat shampoo for fleas and the best cat shampoo for allergies as soon as you find out that your feline baby is suffering from either one of those things.

As a cat mommy or daddy, the first thing you want to do is get rid of the itch right away, but some cat shampoos just get rid of the itch without getting rid of what makes the cat itch! These items are no good because they simply offer a short-term band-aid solution. You should try one of the following shampoos, instead:

Veterinarian William Miller Jr. has explained how ticks and fleas could pose a life threat to cats, especially growing kittens that are still very much vulnerable. This is why it is essential to grab the best cat shampoo for fleas the moment you confirm that your pets are carrying and give a flea bath.

All natural and biodegradable, you need not worry if the Kelco 50:1 Shampoo will pose harmful side effects to your fur babies. It is very safe!

For multi-cat households, the Kelco 50:1 Filthy Animal Shampoo is the ideal since it comes in 5 or 11-gallon containers that will last you for a good amount of time.

Remember that if you are keeping more than one cat, you have to switch all of them to anti-flea shampoo even if just one is confirmed contaminated. You know how those vermin would just jump from one treated host to another untreated one!

Works perfectly for both cats and dogs, the Wahl 100% Natural Pet Shampoo gets rid of the itch and naturally repels fleas and ticks without the use of strong chemicals.

This is a concentrated shampoo, so a few drops should do it especially if you have a small cat. The single side effect the Wahl Natural Pet Shampoo leaves on fur babies is the revitalized coat – you’ll notice positive improvements in your cat’s fur coat after using this! This is a very good side effect especially given that fleas also result to fur damage and hair loss, according to VetStreet.

Finally, an added bonus is the fragrant smell. Your cat will be sporting an alluring fragrance long after you have weaned using the Wahl 100% Natural Pet Shampoo. The scent is not too strong, though, just mildly fragrant and appealing.

Made from aloe, lanolin, and coconut extract, the Vet-Kem Triple Action Flea, and Tick Shampoo make natural ingredients work wonderfully to repel ticks and fleas. Nevertheless, it is not recommended to use this for kittens that are under the age of twelve weeks.

Aside from relieving and soothing your cat babies from the hellish itch that fleas and allergies bring, the Vet-Kem shampoo will also restore your cat’s skin and fur to its top condition, even after severe damage due to the constant itching and scratching.

It is easy to lather too and has a calming smell that could put your cat at ease even when it is generally not fond of baths. After getting rid of the ticks and itches, your cat will surely receive compliments on how shiny their coat has become, thanks to the wonders of the Vet-Kem triple action shampoo.

The best cat shampoo for fleas or allergies is one that does not damage your can’t skin or coat in the process of getting rid of ticks and itches. In fact, The Green Life has already warned about some chemicals present in some shampoos that might be detrimental to the health of your beloved feline. Luckily, the Lambert Kay Fresh ‘n’ Clean Shampoo is made up of only natural pyrethrins.

Even the smell will convince you that there is nothing harmful about this shampoo: the fragrant scent it produces and leaves on your cat will last for weeks after last use.

Instead of having negative side effects on your cat, this shampoo will even condition and treat your cat’s fur. Your cat will even be fluffier and cuter after you use the Lambert Kay Fresh ‘n’ Clean Flea and Tick Small Pet Conditioning Shampoo!

Other flea shampoos do not have the ability to also kill eggs and larvae, which could be very problematic because that may translate to an endless cycle of eggs hatching and your cat itching. The Adams Plus Flea and Tick shampoo, however, is an all around flea protection shampoo that gets even the eggs and the larvae.

If you are thinking that this level of protection and treatment must mean that the shampoo contains loads of strong chemicals, this is not the case. You will only find oatmeal, lanolin, aloe, and coconut extract in this wonderful shampoo. 

A piece of advice: keep your feline outdoors for at least 24 hours after use of this shampoo. Forgetting to do this will leave a site of dead ticks and fleas in your living room, and even in your bedroom, if you let your cat hang out there – yikes!

While other shampoos require lathering and getting your cats fully wet, the Vet’s Best Natural Anti-flea shampoo uses an easy spray which is ideal for cats that just would not get wet for a full bath. (Curious about this? Cat expert Pam Johnson-Bennett explains why most cats simply won’t take a bath right here.)

This shampoo gets fleas on contact, so immediate relief will follow. You can soothe your cat’s itch very quickly with the Vet’s Best Spray Shampoo. Peppermint oil and clove extract are the main ingredients for this shampoo, so no worries of harsh side effects and whatnot.

Only thing: since it kills fleas on contact, you have to make sure you get every spot. Otherwise, you run the risk of all the fleas flocking to the area you miss, and simply regrouping from there – no good!

SynergyLabs Groomer’s Blend Shampoo/Conditioner

The SynergyLabs Groomer’s Blend Conditioning Shampoo may be a lather-type shampoo, but it is still capable of killing fleas and ticks on contact. Additionally, old and dead skin flakes that get left on the cat’s skin also get removed because of this conditioning shampoo.

All in all, it feels like an overall treatment for your cat’s skin and coat. It is even made to be a moisturizing shampoo that boosts the fur’s shine and luster. The SynergyLabs Groomer’s Blend Shampoo is even pH balanced. Note that our pets are sensitive to these kinds of things, and since human shampoo is set at a lower pH, they should not be used on our cats. (Cat blogger Naomi Millburn also warns against this.)

This one’s also paraben and soap free, so it is guaranteed safe and effective even for the most sensitive of felines.

The Honeydew Natural Pet Shampoo for Dogs, Puppies, and Cats may just be the best cat shampoo for allergies available in the market. It gets rid of the itch first and foremost, no matter what is causing the itch. This is good if you really can’t stand your cat suffering and would love to soothe their nerves in an instant.

Fleas and ticks should still watch out, though, for even without mineral oils and artificial ingredients of any sort, the HoneyDew Pet Shampoo still repels parasites, making sure your cats live a healthy life free from the bloodsucking evil.

Lemongrass and citronella are also part of this shampoo’s list of ingredients, and the wonderful smell they produce help get your cat in a calm mood even while engaged in a bath. Just make sure you prep their fur coat by lathering with warm water first before applying the shampoo.

Vet's Best Natural Flea + Tick Home Spray

Another Vet’s Best Spray Shampoo makes the list, simply because it is way easier to spray cats instead of spending hours coaxing them just to get in a bath tub. Also, unlike other flea shampoos, the Vet’s Best Natural Flea and Tick Home Spray kill every egg and larva along with all the fleas and ticks, ensuring maximum protection and a hundred percent relief from the itch.

It also comes with a non-stain formula that is safe to use with all your furniture, making it easy to use. Imagine you can even apply this on your cat while he/she lounges on the cat condo. It is such a convenient alternative than the bath time that is stressful for both of you.

Finally, it is environment-friendly, so there is no guilt attached to using this to soothe your feline friend's allergies and itch.

Most of these flea shampoos have been the spray or liquid type, but the Wondercide Group presents us with this: a natural shampoo bar. Rubbing this shampoo bar on your cat’s skin may prove to be comforting and may even entice them to stay long for the bath, especially since they’d come to feel that the shampoo bar actually reduces the itch they feel.

Neem is one of the main ingredients in this shampoo bar, which is great when you realize that neem oil is both an antibacterial and anti fungal ingredient, rooting and responding to the root of the itch instead of just being the best cat shampoo for allergies by just reducing the itch.

With all these wonderful benefits, this is still not ideal for cats that would not get wet even just for a little while.

Why Flea Allergy Shampoo is Better?

As we all say, prevention is better than cure. So even if you are yet unsure if your feline family has been contaminated with ticks and fleas, it might be nice to use any of the flea shampoos reviewed above just to make sure. Watching your pet cat suffer from the itch and all the dead skins are really heartbreaking, so try to prevent the multiplication of fleas firsthand.

Most of it has been said above: pH balance, mildness, safety, but the best thing to consider before picking a cat shampoo is of course, what you know about your own cat. Some cats would rather itch than be subjected to a bath, so a spray shampoo might be best, while some actually enjoy the feeling of bar rubs. Whichever is it, trust your instinct since you have known your cat the longest.

Get rid of those fleas today!

Whatever happens, never use a shampoo that is not intended for the use of cats. You may be tempted to do so just to save a few bucks, but the money you’ll spend on veterinary services should it end up being toxic for your cat is simply not worth it. Consult a vet, if necessary.
