Ingredient Quality Assessment

Protein Sources

• Named Meats: Chicken, salmon, lamb, etc., often listed as first ingredients.
• Meat Meals: Provide concentrated protein.
• By-Product Meal: Purina uses named by-product meals (e.g., poultry by-product meal), which include nutrient-dense organ meats and muscle tissue. They do not include hair, hooves, or hide.

Carbohydrate Sources

• Grain-Inclusive: Most formulas use easily digestible grains like rice and corn (a source of protein and energy).
• Grain-Free Options: Limited availability, using ingredients like pea protein and potato.

Special Additions

• LiveClear: Contains a specific egg product with anti-Fel d1 antibodies, derived from immunized chickens. Proven safe for cats.
• FortiFlora: A probiotic (Enterococcus faecium) available as a supplement and in some formulas to support digestive health.

The Science Behind LiveClear

How LiveClear Works

1. Immunization: Chickens are immunized against the Fel d1 protein.
2. Antibody Production: These chickens produce anti-Fel d1 antibodies (IgY), which are passed into their eggs.
3. Food Integration: The antibody-rich egg product is added to the cat food.
4. Binding Action: When the cat eats the food, the antibodies bind to Fel d1 in the saliva, neutralizing it.
5. Result: Reduced active allergen is transferred to the cat's coat during grooming.

Published Research

A 2019 study in the Journal of Feline Medicine and Surgery involving 105 cats over 10 weeks found:

• 97% of cats showed decreased Fel d1 levels.
• 47% average reduction in active Fel d1.
• No negative health effects observed in cats.

Frequently Asked Questions (FAQ)

Q: Does LiveClear really work for cat allergies? A: Yes, published research confirms it. While it doesn't eliminate allergies, it significantly reduces the primary allergen (Fel d1) by an average of 47%, allowing many allergic individuals to live more comfortably with cats.

Q: How is Pro Plan different from Purina Cat Chow? A: Pro Plan is a premium line with higher protein content, more specialized formulas, and advanced research behind each recipe. Cat Chow is a more economical, general maintenance diet.

Q: Are by-products in Pro Plan low-quality? A: No. Purina uses named by-product meals (e.g., poultry by-product meal), which are concentrated sources of protein including nutrient-rich organ meats. They are a safe and nutritious ingredient.

Q: Can I mix LiveClear with other food? A: For maximum allergen reduction, feed LiveClear exclusively. Mixing will dilute the antibody content and reduce effectiveness.

Q: How long does it take for LiveClear to work? A: Most cats show reduced allergen levels within 3 weeks, with full effect typically seen by 6-8 weeks of exclusive feeding.

Q: Is regular Pro Plan good for cats with kidney disease? A: No. Cats with kidney disease require a specific therapeutic diet like Pro Plan NF (Kidney Function), which has restricted phosphorus. Always consult your vet before dietary changes for a medical condition.
