Rapamycin for Cats — Feline Longevity Therapy
Once-weekly, delayed-release rapamycin protocol for cats. Weight-calibrated dosing, veterinarian-prescribed.
The cat you love is worth fighting for
Aging in cats is not a mystery anymore. The biology behind heart disease, kidney decline and cancer risk runs through one central pathway — and rapamycin is the most studied molecule we have for targeting it.
What rapamycin therapy actually costs
Shown in your local list price. You are charged this amount at checkout.
Prescription medicine. Your order begins with a licensed veterinarian’s review — nothing is dispensed without it.
Why rapamycin for cats
- Heart — hypertrophic cardiomyopathy (HCM) is the most common heart disease in cats. Recent clinical research suggests rapamycin can slow its progression — a first for feline cardiology.
- Kidneys — chronic kidney disease affects most senior cats. mTOR inhibition is under active clinical investigation at veterinary schools.
- Cancer risk — documented benefit signals in feline mammary and squamous cell carcinomas.
- Cellular aging — partial mTOR inhibition activates autophagy, the cell’s cleanup process, reducing systemic inflammation.
How the therapy works
One delayed-release, acid-resistant tablet once a week, with food. Dosing is calibrated to your cat’s body weight (0.4 mg, 1.2 mg or 2.4 mg strengths). Flavored oral suspensions — chicken, fish, beef — are available for cats that refuse tablets.
Veterinary oversight, included
This is a veterinarian-directed therapy program. Every Rapavie order includes a licensed veterinarian’s review of your cat’s health history, personalized dosing, and ongoing monitoring guidance. Medication is dispensed under veterinary prescription. Lab-tested to a 99.9% purity standard.

Rapavie and Rapamune are the same molecule, not the same medicine

What cat owners say
Individual results vary. These are members’ own experiences, not medical claims or expected outcomes.
Miso is 14 and honestly moves like she did at 8. The vet check-ins make me feel like we’re doing this properly.
The onboarding was so thorough — real vets, real answers. Pamuk approves of the therapy too.
Sisu was diagnosed with early HCM. Between our cardiologist and the Rapavie vets, we finally feel like we are doing something instead of waiting.
What sold me was the honesty. They were clear that it is a prescription medicine reviewed by a vet, not a supplement. That is exactly why I trust it.
The quarterly lab reviews make me feel like my cat has a whole care team. Being able to message a vet the same day is worth it on its own.
Yuki refuses every tablet ever invented, so the flavoured suspension was the deciding factor. Dosing morning is no longer a wrestling match.
