How It Works
What Is Feld1 and Why It Matters
Feld1 is the main protein that cats shed in their saliva. Every time your cat grooms, the protein spreads onto the fur, then flakes off as dandertiny airborne particles that trigger most human cat allergies.
The Science Behind LiveClear and Similar Formulas
LiveClear uses a patented IgY nanobody technologytiny, eggderived antibodies that latch onto Feld1 and neutralize it before it can become airborne. The diet also packs a probiotic blend that supports gut health, which research shows can further calm the cats allergen production.
RealWorld Efficacy: Studies and Surveys
Purinas own clinical trial (50 cats, 21day feeding) reported a 35% reduction in Feld1 on dry food and about 50% on the wet version. A followup survey from the American Academy of Allergy Ophthalmology (AAOA) found 47% of participants felt a definite drop in symptoms after a month of feeding their cats LiveClear.

| AAOA patient panel | 4 weeks | 4060% (subjective) | 30 families | Selfreported relief |

FAQs
How long does it take to notice a reduction in allergy symptoms?
Most owners see noticeable improvement within 2‑3 weeks of feeding a cat a diet specifically designed to reduce Fel d1, though full benefits may appear after a month.
Can any cat benefit from allergen‑reducing food, or only certain breeds?
The diet works for all cat breeds because Fel d1 is a protein produced by every cat’s salivary glands, not a breed‑specific allergen.

Gradual transition is recommended (e.g., 25% new food mixed with current food, increasing weekly) to avoid digestive upset.
Do I still need air purifiers and regular cleaning if I use this cat food?
Yes. While the food lowers dander, combining it with HEPA filters, frequent vacuuming, and regular washing of bedding maximizes relief.
