Cat Allergies: It's Not the Hair – IMSS Reveals the Real Cause

For those who experience sneezing and watery eyes upon entering a home with a cat, the culprit isn’t necessarily what many believe. The Instituto Mexicano del Seguro Social (IMSS) Bienestar recently revealed the true cause of feline allergies and the answer may challenge common assumptions.

The Real Source of the Allergy

Beyond the Fur

On Friday, February 20th, the IMSS Bienestar announced that cat allergies aren’t triggered by a cat’s fur itself. Instead, the primary allergen is a protein called Fel d1. This protein is responsible for up to 96 percent of allergic reactions in humans.

Did You Know? The Fel d1 protein is transferred to a cat’s fur through saliva during grooming.

The IMSS explained that when cats groom themselves, the Fel d1 protein is deposited onto their coat via saliva. This protein then becomes airborne and is easily inhaled by sensitive individuals.

How the Body Reacts

Upon contact with the Fel d1 protein, the system inmunológico identifies it as a threat, initiating an allergic response. Common symptoms, which can last for more than 15 days, include constant sneezing, nasal congestion, itching in the eyes, nose, and throat, and irritation and tearing of the respiratory passages.

Expert Insight: Identifying the specific allergen—Fel d1—is a crucial step in understanding and potentially managing cat allergies. This knowledge allows for a more targeted approach to symptom relief and environmental control.

The IMSS recommends seeking evaluation at a medical unit or a Unidad de Salud IMSS Bienestar. This is particularly important for individuals with asthma or pre-existing allergies, as Fel d1 can cause severe inflammation, potentially leading to chronic rhinitis, asthmatic crises, or even anaphylaxis. Maintaining adequate environmental control by reducing the accumulation of hair, dander, and saliva is also advised.
