About Us

Why We Only Make Supplements for Cats

The supplement industry treats cats like small dogs — same formulas, lower doses, different label. But cats have unique metabolic pathways, sensitivities, and nutritional needs that demand their own approach. Billi Pet exists because we refused to cut that corner.

Every formula is built from scratch around feline biology, using ingredients like Hydrolyzed Fish, Norwegian Salmon Oil, and L-Lysine that cats actually absorb and benefit from.

What Drives Every Formula We Make

Feline Biology Comes First

Cats metabolize ingredients differently than dogs. Our formulas are researched and built around how cats actually absorb nutrients — not scaled down from another species.

More Product, Less Markup

Each jar contains 120 scoops — a full 4-month supply. Most competitors give you 60 for the same price. We'd rather over-deliver than overcharge.

Transparency Over Marketing

Every batch is third-party tested in an FDA-registered, GMP-certified facility in Florida. No proprietary blends, no hidden fillers — just ingredients you can read and verify.

Formulated With Veterinary & Scientific Expertise

Our supplements are developed in partnership with veterinary professionals and food scientists at our FDA-registered manufacturing facility in Florida. Every formula goes through rigorous review to ensure proper ingredient selection, dosing accuracy, and feline-specific bioavailability — so your cat gets exactly what they need, nothing they don't.
