Keep the Cat. Lose the Allergy.


Cat on Couch

If you love your cat but hate the sneezing, itchy eyes, and scratchy throat, you’re not alone. The #1 culprit is a tiny protein called Fel d 1, produced in cats’ sebaceous and salivary glands. It spreads onto fur during grooming and lingers in air and fabrics—triggering symptoms again and again.

The New Allergy Toolkit (That Doesn’t Ask You to Rehome Your Bestie)

Cat Grooming

For years, the playbook was antihistamines, HEPA filters, vacuuming often, and (worst of all) “rehome your cat.” Today, the toolkit is smarter: you can neutralize allergens at the source—on the cat, on surfaces, and in the air— lowering the active allergen load that reaches your nose.

1. Reduce the Allergen at the Source (On the Cat)

Cat Food Bowl

Feeding approaches that target Fel d 1 have peer-reviewed support. Diets with anti-Fel d 1 IgY reduced active Fel d 1 on cats’ hair by ~47% on average in one program. These reductions showed fewer symptoms for sensitive people in exposure tests.

2. Neutralize Allergens in the Home

Pacagen Spray

Room and fabric sprays designed to break down allergens can reduce what’s floating in the air and sitting on surfaces. Pacagen reports up to 98% neutralization of active cat allergens with its Cat Allergen Neutralizing Spray.

3. Keep the Basics, But Smarter

HEPA Filter

HEPA filtration, hot laundry, and strategic no-cat zones still matter. But paired with allergen neutralizers, you get a measurable difference in day-to-day comfort. If symptoms remain significant, consult an allergist.
