What Actually Causes Cat Allergies

What Actually Causes Cat Allergies

Most people blame fur for their allergies. They try more baths, brushing, and vacuuming — but nothing changes.

The real culprit? A tiny protein called Fel d 1 in your cat's saliva.

When your cat grooms, Fel d 1 spreads onto their fur and throughout your home. These microscopic particles float through the air, entering your nose and lungs — causing sneezing, red eyes, and breathing discomfort.

Why Most Cat Allergy Solutions Don't Work

Why Most Cat Allergy Solutions Don't Work

Most solutions don't target Fel d 1 at all. Bathing removes allergens temporarily, but they return after grooming. Air purifiers clean the air but can't stop production. Antihistamines only mask symptoms.

Even allergen-reducing diets like LiveClear dilute proteins throughout a full bag of food. Generic egg-powder supplements contain only trace amounts of IgY. The effect simply isn't strong enough.

Why Pacagen Cat Allergen Reducing Supplement Actually Works

Results You Can Actually Feel

My daughter didn't sneeze!

Every time my daughter would come visit our home, our 2 cats would make her sneeze. I tried the Pacagen spray on all the areas the cats like to lay (rugs, couch, chairs, etc.) and after only a few times, she said she felt much better. No more sneezing! I'm a believer!!

Many people swear by this antibody additive, which can be directly applied as a topper to food. The brand most recommended to me was Pacagen, a powdered additive that should be added to food or fed twice daily.
