Frequently Asked Questions
Will my picky cat actually eat this?
Our base ingredient is Hydrolyzed Fish — not chicken, not goat milk. The fine powder blends seamlessly into wet or dry food without changing the taste or texture. Most cats eat it without even noticing.
How long until I see results?
Most cat parents notice visible changes within 4–6 weeks of consistent daily use. Joint support and immune health benefits build gradually — consistency is key. If no improvement after 6 weeks, try increasing to 2 scoops daily.
How long does one jar last?
Each jar contains 120 scoops. At one scoop per day, that's a full 4-month supply — double what most competitors offer for the same price.
Why powder instead of chews or treats?
Powder delivers the most accurate dosing and lets us include clinical-strength amounts of every ingredient without fillers, binding agents, or artificial sweeteners required in chews. Mix it into food — your cat doesn't know it's a supplement.
Can I use multiple Billi Pet supplements together?
Yes. All three formulas — Hip & Joint, Digestive & Probiotic, and Allergy & Immune — are designed to complement each other. Simply add one scoop of each to the same meal.
Is this safe for kittens or cats with health conditions?
Our formulas are designed for adult cats. The Hip & Joint formula contains shellfish-derived ingredients (Glucosamine, Green Lipped Mussel). For cats under 12 months or with existing health conditions, consult your veterinarian before use.
Where is this made?
All Billi Pet supplements are manufactured in an FDA-registered, GMP-certified, SQF-certified facility in Florida. Every batch is third-party lab tested for purity, potency, and safety.
What is your return policy?
We offer a 30-day money-back guarantee. If you or your cat aren't satisfied, contact us for a full refund — no questions asked.
