Ingredient Quality
We avoided artificial colors, flavors, and preservatives. Whole meats and named meat meals scored higher.

Section 05
Care, Cost and Maintenance
Transition Slowly
Mix new food with old over 7-10 days to avoid digestive upset. Start with 25% new, 75% old, gradually increase.
Monitor for Reactions
Watch for itching, vomiting, or diarrhea when introducing new food. Stop if symptoms persist and consult your vet.
Store Properly
Keep dry food in a cool, dry place in an airtight container to maintain freshness and prevent rancidity.
Pro tip
If eggs were part of your kitten's diet before, LiveClear may be even more effective. Start with a small bag to see if your kitten tolerates the egg protein.
Frequently asked questions
Can I use LiveClear food for my adult cat too?
Purina has adult formulas. The kitten versions meet growth requirements, but you can switch to adult once your cat is one year old.
How long does it take to see allergen reduction?
Manufacturer suggests 3 weeks of consistent feeding for noticeable reduction. We saw improvements in 2-4 weeks.
Is Hill's salmon formula good for chicken allergies?
Yes, salmon is a novel protein and often recommended for chicken-sensitive kittens. It also includes prebiotics for digestion.
What if my kitten has multiple food allergies?
Consult your vet for an elimination diet. These picks are starting points; your vet may recommend a hydrolyzed protein diet.
Are these foods grain-free?
No, they contain grains like rice or oatmeal. Grains are not common allergens, but if your kitten has grain intolerance, look for grain-free options separately.
