Living With Cat Allergies: Symptoms, Reducing Allergens and Options

By Tailwisp Editorial TeamUpdated October 20, 20264 min read

Millions of people love cats and are allergic to them. For some, symptoms are mild, for others they are debilitating. Living with cats while managing allergies is possible for many, but it takes a plan, patience and honest conversation with a doctor.

What causes cat allergies?

The main allergen is Fel d 1, a protein produced mainly in a cat's skin, sebaceous glands and saliva. When cats groom, saliva dries on fur and flakes off as dander. The allergen is sticky and tiny, so it drifts in the air and clings to clothing, furniture and walls. Other cat proteins can also trigger reactions. Fur itself is not the allergen, but it carries the proteins around.

Symptoms

• Sneezing, runny or stuffy nose
• Itchy, red, watery eyes
• Coughing, wheezing or shortness of breath
• Itchy skin, hives or rash after contact
• Facial pressure
• Fatigue

Allergies can trigger or worsen asthma. Seek urgent help for severe breathing problems. See an allergist for diagnosis and treatment.

Talk to a doctor first

Before getting a cat, or if you already have one and are struggling, see a doctor or allergist. They can test, discuss medications and advise on safety, especially for people with asthma. This is general information and not medical advice.

Spend time with the cat

Allergen levels vary between individual cats, regardless of breed. Spend time with a specific cat, at a breeder's or shelter, before committing. Consider fostering. See hypoallergenic cat breeds: the truth.

Reducing allergens at home

Create an allergen-free zone. Keep the bedroom cat-free, with the door closed. Use dust-mite-proof covers.

Clean often.

• Vacuum with a HEPA-filter vacuum several times a week.
• Wash bedding, throws and curtains regularly in hot water.
• Damp-dust surfaces, since dry dusting spreads allergens.
• Choose hard floors over carpet where possible.
• Wash cat bedding weekly.

Filter the air.

• Use a HEPA air purifier in main rooms and the bedroom.
• Change HVAC filters regularly, and consider high-efficiency filters.

Wash your hands after handling the cat, and avoid touching your face.

Keep litter clean. Dust from litter can irritate airways. Use low-dust litter. See how to choose cat litter and how often to clean a litter box. Ask someone without allergies to clean the box if possible.

Grooming and bathing

Regular brushing removes loose fur and dander. See how to brush a cat. Brush outside if possible, and wear a mask. Frequent bathing is controversial. Some studies suggest a short-term reduction in allergen levels, but it may stress the cat and irritate skin. See how to bathe a cat. Wipes can help in between.

Diet and products

Some diets and products claim to reduce Fel d 1. Evidence is emerging for specific products, so ask your vet and doctor. Be careful with claims that sound too good to be true.

Medical options

• Antihistamines and nasal sprays
• Eye drops
• Asthma medication
• Allergy shots, or immunotherapy, which can reduce sensitivity over time

Discuss options with an allergist.

Breeds

Some breeds, such as the Siberian, Balinese, Sphynx and Devon Rex, are often suggested for allergic people. Individual reactions vary, and none is allergen-free. A cat's sex, age and neuter status can also affect allergen production.

Think before you rehome

Giving up a beloved pet is painful. Try these steps before making that decision, and seek medical support. If rehoming is necessary, work with a reputable shelter and be honest about the reasons.

Realistic expectations

Even with the best plan, some people continue to have symptoms. Keep a diary of symptoms, triggers and what helps. Share it with your allergist, and review your plan every few months. Some people find that symptoms improve over time as they get used to a cat, while others find them worsening. Be honest about how you feel, and ask for help.

Children and allergies

Early exposure to pets may reduce the risk of allergies in some children, but it is not guaranteed, and children who are allergic need medical guidance. Talk to your pediatrician before bringing a cat into a home with a child who has asthma or allergies.

Day-to-day habits that help

Change clothes after heavy cuddling, keep a lint roller handy, wash your face before bed and rinse your hair if you have been close to the cat. Use washable covers on sofas, and wipe hard surfaces regularly. Small habits add up, and together they can bring symptoms down to a tolerable level.

Cat-friendly home

Create a home that works for the cat and the allergic person. See cat-friendly home setup. Use the US vet directory to find a vet who can advise on grooming and skin health.
