What Can I Give My Cat For Allergies

The days went by, spring and summer. Fleas grow headlining. Tree in full bloom. Pollen flying everywhere. And your cat may be allergic. This is a genetic predisposition and usually begins to show when the cat is 1 to 3 years old.

Cats are very good at hiding signs of their health effects. But when allergies begin, cats cannot hide excessive itchiness or redness under the eyes. It’s a fact that you don’t have a permanent cure for cat allergies. But we can recommend some solutions for preventing and overcoming cat allergies.


In cats, the most common allergy is more skin diseases than respiratory diseases like humans. So, what can I give my cat for allergies? An allergy in cats is an overactive reaction of the immune system when the body exposed to foreign substances (triggers). Sometimes we see respiratory symptoms due to allergies, but in general, an allergic cat often presents with itching. They may have bald spots or sores, scabs on the skin.

The best treatment depends on the cause of the allergy. Eliminating is the best treatment for flea allergies. Atopy dermatitis is treated by avoiding (if possible) and sometimes using anti-inflammatory drugs or “anti-allergy injections” that help cats to be immune to allergens. Remedy for food allergies is avoiding the use of food ingredients that cause allergies.

What is an allergy?

The human immune system is responsible for protecting the body against viruses, bacteria, and fungi, and the same for cats, the immune system removes harmful substances from entering the body. It also prevents any infectious organism from entering the cat’s body. If the immune system is impaired, it cannot respond to something harmful that comes into contact with the cat’s body. That is the cause of allergy.

The reasons why cats are allergic?

There are 3 common causes of cat allergies: Skin allergies caused by flea bites, food allergies, and allergies to the environment.

1. Allergy in cats caused by fleas (this is a very common allergy)

The main reason is that saliva secreted from flea bites on the skin and transmitted to the cat’s skin by fleabites leads to itching. The main food of a parasite under the skin of a cat is the blood of an animal, so the host injects some saliva into the skin during suctioning from the host. Then, protein in the saliva causes a strong reaction and makes the host itchy).


In cases like these, cats often scratch a lot in the itch causing open wounds or scabs on the skin leading to a secondary bacterial skin infection (pyoderma). The most common area is on the buttock or tail base. Besides, cats may have small scales around their head and neck. These scales are miliary dermatitis (scales that look like millet seeds).

2. Cats are allergic to food

Manifest: itchy skin, digestive disorders, vomiting, or diarrhea. In some special cases, cats may appear as weight loss, weakness.

Almost any food ingredient can cause a cat allergy, of which the most common cause is protein and some other additives. Especially dairy products, beef, lamb, chicken, chicken eggs, soy, or gluten (from wheat and corn) are the most cat allergies.

3. Allergies to the environment

Substances that can cause allergies in cats when inhaled or exposed include pollen of weeds (ragweed), plants (cedar, ash, oak …), mold, dirt in the air.

Symptoms of allergic disease in cats

The four main symptoms are redness, body heat, swelling, and itching. An allergic cat often scratches, licks, bites, or chews on their feet, flanks, ears, armpits, and groin, causing patchy and reddened hair loss.

Some cats even rub their faces on carpets, causing their ears to turn red (because the wax glands in the ears produce a large amount of waste and become an allergen, bacterial infection, and Malassezia yeast in the ear). Cats may develop rashes or sores on the skin.

If the cat is very sick, it can cause hair loss, affect the pigmentation of the skin and cause an unpleasant odor. The cat also has many small scales on the skin that cause hair loss (especially on the back), and cause pain (especially on the face).

For allergies caused by food, in addition to some of the symptoms mentioned above, it also affects the digestive tract causing pain, flatulence, and even diarrhea.

Some signs of allergies in cats

  • It causes itching, pain, unpleasant odors of allergic skin areas.
  • Affects the digestive tract causing pain, diarrhea, and flatulence.
  • As one of the causes of chronic ear infections.
  • An allergic cat can lead to coughing, sneezing, and wheezing.
  • The disease can cause cats to be thinned and even shed hair and have an unpleasant odor.

What Can I Give My Cat For Allergies?

You should take your cat to see a veterinarian make sure the condition is not getting worse. That’s the first thing you should do. When a cat is diagnosed with an allergy, the veterinarian will have specific consultations with helpful prescriptions and advice based on the specific cause.

Besides the useful prescription of veterinarians, we also propose some solutions to overcome cat allergies by specific causes. Of course, in all cases, the best remedy is to prevent cat irritants.

Treat flea regularly

Beware of fleas on the cat’s skin and preventive treatment for them. By the time fleas are booming (especially in the spring and summer), you may need to take your cat to see a veterinarian. They will then apply a special gel on your cat’s skin to aid in the ticking of the flea, and it will last for 3 months.

What can they give your cat for flea allergies? When the cat’s allergy symptoms are too severe, the veterinarian will prescribe a medicated shampoo and antibiotics. If your cat gets overly inflammation, asteroid or antihistamine course is essential.

Change the composition of cat food

Like other allergies, there is still no treatment for food allergies. Once the vet has a clear diagnosis, you should avoid food that causes an allergic flare instead of letting the cat continue to eat them.

We recommend that you consult with your veterinarian to find a portion of more suitable food for your cat instead of feeding him allergy-causing foods. Each cat has a different level of tolerance to allergies. So, some cats may “get familiar” with continuing to eat the old food. But some cats cannot proceed with this “taste,” and they show signs of vomiting.

Change in the family

Common causes of allergies in cats are grass, mold and airborne irritants. To avoid this, close the windows and change the air filter. You should also clean your pet when coming in from outside. Floors should be dusted with a damp cloth or regularly cleaned. The most important thing is to clean your cat’s home regularly with hot water and thoroughly wash detergents from around the house.

What medicine can I give my cat for allergies? That’s a question I often ask when cats are allergic to the environment. A prescription of cortisone or steroid is essential if symptoms detected are from pollen in the air. Besides, you can also inject histamine antibiotics as a preventive method.

Final Thoughts

It’s hard to know precisely what causes cat allergies because they can be caused by a variety of factors. So, what can you give your cat for allergies? To prevent it, you should change or clean some objects around your cat’s home and shelter to ensure your cat’s health. But above all, we encourage you to take your cat to see your veterinarian for the most helpful prescriptions and advice.
