Support for Cats with Allergies

Cats can have seasonal allergies just like people. A cat’s immune system will respond and react to everyday allergens found in the environment. Like people, cats can have an allergy to pollen, mold, grass, ragweed, and dust mites. They can also be allergic to certain household products such as cleaners, carpet fibers, carpet deodorizers, insecticides, rubber, and other things in the form of contact dermatitis. Your pet’s immune system might overreact to these common unharmful environmental substances.

How NHV Supplements Soothe Allergies in Cats

You can help support your pet’s immune reaction to these airborne irritants by using herbal supplements. Made with powerful, yet gentle ingredients such as eyebright, feverfew, and Sweet goldenrod, Alge-Ex helps to soothe your cat’s histamine response. This remedy for cats with seasonal allergies is vet-formulated and pet-approved. It's 100% natural and completely safe to be taken along with conventional medicine, and easy to administer. Order NHV supplements today, or contact us to speak with one of our pet experts about the best natural remedies for your cat.

Additional Support

It’s best to ensure that your pet is not dealing with skin allergies due to food allergies. If you suspect this, try a different brand of food that is clean, holistic, and without preservatives.

Bathing your pet is also an excellent way of helping your cat cope with seasonal allergies. Bathing helps remove pollen, mold, and other allergens on cats and also provides relief. Make sure to give your pet plenty of filtered water.

Never attempt to diagnose your cat on your own. Your vet will be able to perform the required test and make the necessary suggestions.

Eyebright - An herb that has a long history of use for its anti-inflammatory, antibacterial, antifungal, anti-catarrhal, and antiviral activities. Due to the anti-inflammatory properties, eyebright is used for upper respiratory tract infections, hay fever, sinusitis, and catarrh (inflammation of the mucous membranes). As an astringent, it is used for dry congestion. It is considered to be useful for seasonal allergies, pollen, and mold allergies in cats. It also relieves itchy eyes.

Ginger - A pungent and aromatic root used as a spice to enhance flavor in food. The part used is the rhizome, which has been used for thousands of years for nausea and gastrointestinal relief. Research has shown that ginger has excellent antioxidant and anti-inflammatory properties.

Feverfew - An herb originally native to Eastern Europe, it has been used to reduce migraines. Studies have shown that Feverfew inhibits the release of histamine and serotonin. It is considered to be very safe for cats and is used as an alternative to aspirin, which can be toxic to cats.

European Goldenrod - An herb with anti-inflammatory, anti-catarrhal, and antioxidant properties. It helps increase renal blood flow and glomerular filtration rate without stimulating the loss of sodium and chloride.

Echinacea - In human and animal experiments, Echinacea preparations have been shown to have immunostimulant effects. Its defense against microorganisms help the body fight infections and remove invading bacteria. Echinacea also supports the lymph system, which in turn expels waste from the tissues.

What are the common symptoms of seasonal allergies in cats?

Cats with seasonal allergies will often have runny eyes, nasal congestion, and itchy skin.

What is histamine?

Histamine is a substance created by the immune system in defense of foreign material. In cats with seasonal allergies, histamines can cause runny eyes and nose, sneezing, and itching, all of which can potentially help the body to flush out the foreign materials. Sometimes histamines are helpful, protecting the body against actual threats. While other times, the immune system overreacts and releases histamine when it is not needed.

I'm not sure if my cat has seasonal allergies, but I want to try this supplement. Could this cause my cat’s immune system to overreact if my cat doesn't have allergies?

Alge-Ex is safe to give to pets who do not have any known allergies. The herbs help to balance the immune response. They will not cause this immune response to over or underreact.

What is the difference between Alge-Ex for cats and Alge-Ex for dogs?

Our supplements are listed as 'for cats' or 'for dogs' for ease of searching for pet parents. They actually are the exact same product. The difference is in the dosing, which is by weight.
