How can I tell if my cat has allergies?

If your cat has allergies, some of the most common allergic reactions in cats cause the following behaviors, conditions, and symptoms:

  • Sneezing, coughing, and wheezing.
  • Itchy, running eyes.
  • Ear infections.
  • Vomiting or diarrhea.
  • Snoring.
  • Swollen, sensitive paws.
  • Excessive licking (grooming)
  • Red or dry skin.

Excessive Scratching and Licking: One of the most prominent signs of allergies in cats is excessive scratching, licking, or biting themselves. If you notice your cat obsessively grooming a specific area, it could indicate an allergic response.

Skin Irritation: Allergic reactions often lead to redness, swelling, and skin irritation. If you notice your cat has developed rashes or small bumps on their skin, allergies could be the culprit.

Hair Loss: Continuous scratching and licking due to allergies can result in hair loss, leaving patches of exposed skin.

Sneezing and Coughing: Just like humans, cats with allergies might experience sneezing fits or coughing. If these symptoms are persistent, allergies could be a likely cause.

Watery Eyes and Nose: Allergies can also manifest as watery or teary eyes and a runny nose in cats.

Ear Infections: Allergic reactions can lead to increased moisture and inflammation in a cat’s ears, making them more susceptible to ear infections.

Gastrointestinal Upset: Some cats might exhibit gastrointestinal symptoms such as vomiting or diarrhea as a result of allergies, although these are less common.

Behavioral Changes: Allergies can make cats uncomfortable, leading to changes in behavior. Your cat might become more irritable, lethargic, or withdrawn.

How do you treat a cat with allergies?

How Allergies In Cats are Treated

  • Prescription shampoo or ear flushes.
  • Anti-inflammatory topicals.
  • Oral antibiotics.
  • Injectable prescription medication.
  • Corticosteroid therapy (especially for asthmatic cats)
  • Allergen-specific immunotherapy (a.k.a. allergy shots) for severe cases.
  • Prescription dietary supplements.

Immunotherapy (Allergy Shots):

In cases of severe allergies, your veterinarian might recommend immunotherapy. This involves gradually exposing your cat to small amounts of the allergen over time to build up their immunity and reduce allergic reactions.

Regular Grooming:

Regular grooming sessions can help reduce allergens on your cat’s skin and coat. Brushing can remove loose fur and dander, promoting healthier skin.

Stress Management:

Stress can exacerbate allergy symptoms. Providing a calm and enriching environment for your cat can support their overall well-being and immune function.

Monitor and Adjust:

Keep a close watch on your cat’s response to treatments. If there’s minimal improvement or new symptoms arise, consult your veterinarian for adjustments to the treatment plan.

What is the fastest way to get rid of cat allergies?

One way to reduce cat allergies is limiting exposure to cat allergens. This includes cleaning more often and limiting the rooms your cat is allowed in. The best way to get long-term relief is through allergy immunotherapy which retrains your immune system to stop being allergic.

Designated Cat-Free Zones

Creating specific areas in your home where your cat is not allowed can help reduce your exposure to allergens. Ideally, these areas should include bedrooms, as spending one-third of your day in a cat-free environment can greatly alleviate symptoms.

Regular Cleaning

Frequent cleaning can significantly reduce allergen buildup in your home:

Vacuuming: Use a vacuum cleaner equipped with a HEPA filter to effectively capture allergens from carpets, upholstery, and floors.

Dusting: Regularly dust surfaces and shelves to minimize allergen accumulation.

Washing: Wash your cat’s bedding, toys, and your own bedding in hot water to remove allergens.

Air Purifiers

Invest in high-quality air purifiers with HEPA filters to trap airborne allergens and improve indoor air quality.

Grooming Your Cat

Regular grooming can reduce the amount of allergens on your cat’s fur:

Brushing: Brush your cat’s coat frequently to remove loose fur and dander. Brushing can also distribute natural skin oils that help keep their skin healthy.

Bathing: While not all cats tolerate baths, bathing your cat occasionally can remove allergens from their fur. Consult your veterinarian for guidance on cat-friendly bathing techniques and products.

How can I reduce cat allergies at home?

Get your cat used to being groomed outdoors, away from soft furnishings. Wipe them with a damp cloth or anti-allergen wipes to remove allergens from their coat. Follow hygiene practices when handling your cat. Avoid letting your cat lick your skin or clothes, and always wash your hands after petting them.

Allergen-Reducing Products:

Use allergen-reducing sprays or wipes designed for furniture, carpets, and other surfaces to neutralize allergens.

Wash Hands and Change Clothes:

After interacting with your cat, wash your hands thoroughly and change into clean clothes to prevent transferring allergens to other surfaces or yourself.

HEPA Filtered Vacuum:

Consider using a vacuum cleaner with a HEPA filter to effectively remove allergens from your home.

Minimal Upholstery and Carpets:

Opt for furniture with smooth surfaces and minimal upholstery, as these are less likely to trap allergens. If possible, minimize the use of carpets or choose low-pile carpets that are easier to clean.

Frequent Litter Box Cleaning:

If you have a cat litter box, clean it daily to prevent allergens from spreading.

Consult an Allergist:

If your allergies are severe, consider consulting an allergist for personalized advice, allergy testing, and potential immunotherapy options.

What season are cat allergies worst?

Dogs and cats may be your best friends, but, if you have allergies, they could be your worst enemy, especially in the winter. As the weather gets colder and dogs and cats spend more time inside, the level of animal dander rises in the home.

Spring and Summer

Spring and summer are notorious for increased outdoor allergen levels, particularly pollen. While cats primarily live indoors, they can bring pollen and other outdoor allergens into your home on their fur. Open windows and doors during these seasons can allow allergens to enter, further aggravating symptoms. Additionally, higher humidity levels can contribute to the growth of indoor mold, another allergen source.


Fall brings about changes in foliage and increased outdoor allergens, such as ragweed pollen. As cats continue to move between indoor and outdoor environments, they can carry these allergens indoors, leading to heightened allergy symptoms.


Winter is generally a better season for cat allergy sufferers due to lower outdoor pollen levels. However, spending more time indoors during cold months can increase exposure to indoor allergens like dust mites, pet dander, and mold, which thrive in warm and humid environments.

Do cat allergies go away?

Although cat allergy symptoms may never go away completely, they are manageable. Remember this basic fact about cat allergens. They need to be airborne and you need to breathe them in for you to have an allergic reaction to them. Cat allergen is very small so it remains suspended in the air longer.

Potential Changes Over Time

Gradual Tolerance Development:Some people who are mildly allergic to cats may experience a gradual increase in tolerance over time. Exposure to low levels of allergens might lead to a reduced sensitivity in some cases.

Immune System Adaptation:The immune system can, to some extent, adapt to repeated exposure to allergens. This adaptation could result in milder allergic reactions over time.

Individual Variation:Individuals’ responses to cat allergens can vary widely. While some might see an improvement in symptoms, others might not experience significant changes.

Childhood Allergies:Some children with cat allergies might outgrow their sensitivity as they age. However, this is not guaranteed and varies from person to person.
