About
Cats deserve longevity science too.
The longevity supplement industry has exploded for humans. Brands like Blueprint, IM8, and AG1 have turned aging research into billion-dollar consumer products. The science is real. The demand is real.
But when we looked at the cat supplement market, we found a gap that surprised us: not a single product was built on the strongest evidence available — the Cupp lifetime feeding trial.
We built Whisker9 starting from that foundation. Then we layered in modern longevity compounds — NR for NAD+ restoration, quercetin for inflammation, CoQ10 for mitochondrial support.
We publish every ingredient, every dose, and the evidence level behind each one. Because hiding behind proprietary blends is what the rest of the industry does, and it's not good enough.
Our principles
Evidence first
Every ingredient must be justified by published research. We categorize evidence into three tiers and tell you which level each ingredient falls into.
Full transparency
We publish exact doses, sourcing details, and the scientific rationale for every ingredient. No proprietary blends. If we can’t defend it publicly, it doesn’t go in the formula.
Cat-specific
Cats are not small dogs. They can’t synthesize taurine. They lack glucuronidation pathways. Alpha-lipoic acid is lethal to them at doses safe for humans. Every formulation decision accounts for feline physiology.
Simplicity
One product. One scoop. Every day. We don’t sell a confusing lineup of SKUs. We sell the best formula we can make, and we make it easy.
