These Are The Best Medications For Cat Allergies

Cats can develop allergies in the same manner that humans do. Allergies occur when the immune system becomes hypersensitive to a certain chemical.

These allergies may not harm your other pets, you, or human family members, but they can cause sneezing, coughing, watery eyes, and even vomiting or diarrhea in your cat.

Pollen, grass, and other environmental allergies; corn, eggs, and other foods; or flea, worm, and prescription treatment are examples of such allergens.

If your cat's symptoms are really severe, you should contact a veterinarian, who will most likely prescribe strong antihistamines.

However, if your cat has moderate symptoms or you prefer not to give them powerful pharmaceutical medication, there are options such as gentler medications and homeopathic therapies.

BestForPets (bestforpets.org) has reviewed the %product_count% best medications for cat allergies below.

Using these evaluations, you can find a remedy to treat your cat's symptoms while identifying and eliminating allergens from their environment.


Seasonal Allergy Herbal Formula for Animals – Best Overall

Cats, like humans, can suffer from hay fever. Hay fever is an allergic reaction to pollen, which is common in the summer.

Itchy and red eyes, sneezing and teary eyes, and skin rashes are some of the symptoms. Given that their eyes are down at grass and flower level, it is surprising that more cats do not present with hay fever.

Animal Essentials Seasonal Allergy Herbal Formula is a cat allergy supplement that contains nettle leaf, eyebright, burdock root, and licorice root as active components.

Vegetable glycerin, water, and grain alcohol are also included in this holistic drink. This cat allergy supplement is safe for both dogs and cats, and cat owners should administer up to 0.25 mL per dose, 2-3 times per day.

Unfortunately, the liquid has a strong odor and appearance, which may make convincing all cats to drink it difficult. However, it has had great results, and a tiny bottle will offer your cat with more than 100 doses.


  • 100% natural ingredients
  • Reasonable cost
  • Relieve hay fever symptoms


  • Noxious odor


Best Price for HomeoPet Nose Relief

This liquid is safe for dogs, birds, small animals, and cats. A single bottle contains enough for 450 drops and can be given directly or mixed into food or water.

Cats need just 15 drops each day, so a box will last about a month, and the price is very inexpensive, making HomeoPet Nose Relief the best prescription for cat allergies for the money.

The natural active substances were chosen not only for their efficiency in alleviating allergy symptoms, but also for their lack of side effects.

As a result, administering HomeoPet Nose Relief liquid to your cat is both safe and effective. This anti-allergen is effective at drying up runny noses and mucous, but it is less effective at treating severe allergy symptoms.


  • Cheap
  • Simple to administrate
  • It aids in the drying of runny noses.


  • Not as effective in treating severe symptoms


Allergy Aid Soft Chews NaturVet Aller-911 Premium Choice

NaturVet Aller-911 Allergy Aid Soft Chews are natural active ingredient soft chews. Flaxseed and fish oil, turmeric root, grape seed, pumpkin, witch hazel, tea tree oil, and aloe vera are all included in the chews.

A bottle is pricey, but the large container of chews has 180 soft chews, which should last your cat for up to three months. The contents do include canola oil, which is a contentious element in any pet food or supplement.

Canola is derived from rapeseed, which is frequently genetically engineered, and the precise impacts of such foods remain unknown.

Some business owners want to avoid using these ingredients. It’s worth mentioning that grape seed extract is included among the components.

While grapes are poisonous to dogs, grape seeds are not. They are, nevertheless, powerful antioxidants with anti-inflammatory qualities, making them suitable for treating allergic skin reactions.

Some cats will refuse the smell or taste of these chews, as is a fairly regular problem with medications.


  • Natural substances are used.
  • Soft chews should be simple to consume.


  • Expensive
  • Canola oil is present.
  • Not all cats enjoy the flavor.


Allergy Aid Hot Spot Plus NaturVet Aller-911

NaturVet Aller-911 Allergy Aid Hot Spot Plus is a dog and cat topical foam. Witch hazel, tea tree oil, and aloe vera extract are among the components.

Cat owners should apply one to three pumps of the foam to damaged regions of their cat’s skin. To achieve the greatest effects, softly pat the foam after application.

It is safe to use up to three times each day. The chemicals relieve itching, redness, and sore places. It is a low-cost foam that can be effective in reducing itching.

It does, however, have a strong tea tree smell, which may deter some cats from licking it off but may be too strong for some cats and humans.

Although the foam may not be suitable for all cats, it should be easier to apply than a pump-action spray.


  • Foam is simple to use.
  • It relieves itching and lowers irritation.
  • Inexpensive


  • Strong tea tree aroma
  • The foam will not appeal to all cats.


Itch and allergy relief from Liquid-Vet

Liquid-Vet Itch & Allergy Support is a liquid allergy supplement for cats that can be given directly or mixed with their food or drink. It has chicken flavor, fish oil, hyaluronic acid, and citric acid to make it more enticing to your cats.

However, its strong odor may turn off some cats, but a bottle will last about a month with daily use and is less expensive than many other allergy supplements.

The omega-3 fatty acids present in fish oil should help significantly lessen the irritation and agitation caused by allergies, which can lead your cat to scratch and even chew their skin.

Liquid-Vet Itch & Allergy Support can be used as a regular supplement or to relieve symptoms while you investigate the cause of your cat’s allergic reactions.


  • Contains omega fatty acids
  • Chicken taste is included.
  • Inexpensive


  • Not all cats like it.


Wondercide Itch + Allergy Relief Skin Tonic

The Wondercide Skin Tonic Itch + Allergy Relief spray is suitable for both cats and dogs.

Active components include neem, lavender, cedar, and lemongrass oils, which provide relief from itching skin caused by allergic responses.

The spray should be administered liberally to the affected region of skin before gently massaging it in. It can be used as many times as needed during the day as long as it offers relief.

There are no artificial additions in the ingredients. It can be used to relieve irritation caused by allergies, dry skin, bed bug bites, and other conditions.

It is more expensive than the majority of the other options on the list, but it comes with either a pump or a spray bottle, depending on the size you purchase.

Despite its rather costly price, the Wondercide Skin Tonic Itch + Allergy Relief spray appears to aid cats with itchy skin, and most pets don’t like the smell.


  • Ingredients derived from nature
  • Allergies and other skin disorders can benefit from skin relief.
  • Excellent spray bottle


  • Expensive

Buyer's Guide: Choosing the Best Cat Allergy Medication

The finest cat allergy medicine can help relieve skin problems such as redness and itching. It can also aid in the treatment of serious symptoms such as vomiting and diarrhea.

Although your veterinarian can prescribe antihistamines and other prescription pharmaceuticals, there are a variety of natural and holistic vitamins and other remedies that can keep you from having to give your beloved feline powerful medication and with fewer side effects.

Allergies to cats

Cat allergies are the same as human allergies. They develop when your cat’s immune system reacts badly to specific foods, beverages, or environmental conditions.

Their immune system perceives the allergen as an attack on the body and responds by battling the alleged sickness. Fleas, food goods, and even particular types of grass can cause allergies.

Mild itching and red eyes are common, as are intense chewing, vomiting, and diarrhea. If left untreated, even minor symptoms can become significant.

If your cat’s itchiness persists in a particular place, they may scratch or bite the area excessively, causing it to bleed. If they continue to irritate the area, the sore may get infected, potentially leading to life-threatening complications.

Treating an allergy as soon as possible will assist to lessen symptoms. This can help you figure out what your cat is allergic to and hunt for alternatives.

Some cat allergy medication and cat allergy supplements are intended to be taken on a long-term basis, providing your cat with lifelong protection.


Cats will exhibit a variety of symptoms that range in severity from bothersome to life-threatening.

Mild signs and symptoms include:

  • Itching
  • Loss of hair
  • Irritation and redness of the skin
  • Sneezing
  • Swelling
  • Coughing
  • Swollen eyes

The following are more severe symptoms:

  • Breathing difficulties
  • Vomiting
  • Wheezing
  • Diarrhea
  • Chewing on irritated spots

The most serious symptoms include your cat’s capacity to breathe. Swelling is one of the ways the body responds to illness.

If the edema happens around the face, throat, or respiratory system, your cat may be unable to breathe normally.

This is problematic in all cats, but especially if your cat already has a condition that makes it difficult for him to breathe regularly, such as asthma.

Itching and skin redness may begin mildly, but with enough scratching and chewing, even mild itching can become a significant problem.

Over-licking or chewing on a sensitive area can eventually result in hair loss. It can eventually lead to open wounds that become infected.

What Are the Most Common Cat Allergies?

Your cat, like humans, may be allergic to a variety of substances. Identifying allergies is the first step in removing them from your cat’s life.

Consider anything new in your cat’s life if an allergic response has recently begun. Have you modified their diet? When your cat goes outside, does he travel to any new places?

Is he sitting on freshly washed laundry, and are you using a new detergent?

Among the potential allergies are:

  • Pollens: Cats, like people, are susceptible to hay fever, albeit it is less common. Given that your cat’s eyes, nose, and mouth are all located near grass and flowers, it’s no surprise that hay fever can have a major influence on his or her health.
  • Food is a reasonably common source of allergies in cats. Eggs and dairy are two of the most frequent food allergens, as are animal proteins like beef and poultry, and grains, but grain allergies are uncommon.
  • Flea allergy is the most frequent allergy in cats. Unfortunately, bites can cause serious reactions such as redness, itching, and hair loss.
  • Medicine: If your cat has recently begun a new medication or therapy, this may be the source of his allergy. For most drugs, see your veterinarian about an alternative.

What Do Vets Prescribe for Cat Allergies?

There are several veterinarian therapies that can help your cat’s symptoms, including:

  • Steroids are commonly used to treat painful and itchy skin. They are quite cheap, but if you do not discover what your cat is allergic to, your cat will almost certainly require regular steroid injections. The expense can quickly pile up, and it may not be covered by pet insurance, and long-term use might result in dangerous negative effects.
  • Itching can also be treated with other drugs. These vary in terms of effectiveness, cost, and any potential side effects.
  • Your cat may be administered antihistamines such as Benadryl. You should never give them without first seeing your veterinarian because over-prescription can be lethal, while under-prescription is ineffectual.
  • Antibiotics will not cure the allergy, but they may be required if your cat has licked, itched, or chewed its skin, causing open wounds.
  • Prescription diets can be used to eliminate some or all of your cat’s food allergies. These can be used as part of your cat’s elimination diet. This entails removing all known allergies before gradually reintroducing them. When your cat exhibits allergic symptoms, you have identified one allergen.

How Can I Naturally Treat My Cat’s Allergies?

There are some natural therapies that may provide some temporary relief from your cat’s allergies.

  • Fish oil is high in omega-3 fatty acids, which increase skin immunity and have anti-inflammatory qualities. Fish oil is a frequent element in many supplements, and it has the added benefit of most cats liking the fragrance and flavor. However, avoid cod liver oil because it contains too many vitamins.
  • Coconut oil inhibits the growth of yeast. Inflammation is frequently caused by yeast. It’s also a potent antioxidant. Coconut oil can be used on sensitive skin as a topical ointment. It is non-toxic, so licking the area will not hurt your cat, whether he likes the smell of coconut or is trying to relieve itching.
  • Chamomile also inhibits the molecules that produce inflammation. Mild yeast and bacteria will also be killed. It can be made as a topical spray and sprayed directly to the affected area.

Guide to Cat Allergy Supplements

You can also purchase cat allergy pills and natural, holistic therapies, such as the ones we discussed above. These are milder than prescription medications and provide some relief from allergy symptoms.

The following are some of the most frequent forms of supplements:

  • A liquid supplement is typically packaged in a container with a dropper or spray. The liquid can be mixed with food or, in extreme situations, sprayed directly into the cat’s mouth.
  • Pills are the most common method of administering medication to cats and other animals. Smaller pills with no odor or flavor can be hidden in a piece of meat or within a pill. Larger pills may require grinding. Alternatively, a pill popper can be used to effectively and safely blast the pill down your cat’s throat.
  • Spray – A spray is a topical solution that is typically administered to irritated or itchy skin areas. Although your cat may dislike the sound of the applicator, these are pretty simple to apply.
  • Foam – Another topical solution is foam. In most circumstances, you apply it directly to the cat’s affected area and then rub or dab it in. Some foams may require lathering before application.
  • Powder – Before giving your cat food or a food-based treat, a powder can be added. Because of the texture of powder, your cat may identify it and avoid it, but it is more difficult to avoid powder than it is to avoid a pill.


While avoiding allergens is the best method, determining the source of an allergy can be tricky, especially if your cat goes outside every day.

Vets can also prescribe and provide regular treatments such as steroid injections, however supplements offer a more empathetic, cost-effective, and long-term solution to the problem.

We discovered Animal Essentials Seasonal Allergy Herbal Formula to be the finest treatment for cat allergies while writing the reviews above because it is affordable, effective, and helps combat the symptoms of feline hay fever.

While HomeoPet Nose Relief does not work as well on severe symptoms, it is inexpensive and efficient at preventing runny noses and minor symptoms.
