RAPAMYCIN FOR CATS — Feline Longevity Therapy
The Cat You Love Is Still In There.
Cats hide their aging well. That's their nature. But you know your cat — and you've noticed. The slower mornings. The window perch they don't jump to anymore. The quietness that wasn't there before.
Rapamycin doesn't just extend life. It has been shown to improve immune function, reduce inflammation, and support the cellular health that keeps your cat feeling like themselves — not just surviving, but living.
Most feline medicine is reactive. Rapamycin offers a proactive pathway for your cat.
But here's what matters most: Dr. Kevin can prescribe it for your cat today. Because waiting for HCM, kidney disease, or cancer is not a strategy.
The First True Longevity Medicine for Cats
|
The Trivium Study: Rapamycin stops HCM progression in cats. The first drug ever shown to modify the course of feline heart disease. |
Four Ways Rapamycin Protects Your Cat.
Rapamycin inhibits mTOR — a central regulator of cellular aging, inflammation, and disease. In cats, at precisely calibrated weekly doses, it targets the four greatest threats to feline longevity:
|
What the Research Shows in Cats: ✓ HCM (HEART DISEASE) — The Trivium study confirmed rapamycin slows and can stop the progression of hypertrophic cardiomyopathy — the #1 killer of adult cats over age 9. Nothing else has ever done this. ✓ CHRONIC KIDNEY DISEASE (CKD) — Rapamycin has been shown to slow CKD progression in multiple mammalian species. Active clinical trials at Ohio State, Florida, and Texas veterinary schools are studying this directly in cats. ✓ CANCER RISK — Rapamycin has been proven beneficial in feline mammary cancer and squamous cell carcinoma. It works by helping the immune system identify and destroy abnormal cells before they establish. ✓ WHOLE-BODY AGING — By targeting mTOR, rapamycin addresses the core biology of cellular aging itself — reducing the systemic inflammation, cellular dysfunction, and metabolic decline that makes cats age faster than they should. |
What Cat Parents Are Saying.
⭐⭐⭐⭐⭐
"Our kitty has been on rapamycin since December and is NOTICEABLY more active, energetic, and playful. Working with Dr. Kevin has been the best investment in our little bud's happiness — and ours."
— Verified Buyer, Early HCM Cat
⭐⭐⭐⭐⭐
"I was terrified our HCM kitty Patch didn't have much time left. After working with Dr. Kevin and starting Rapamycin, Patch is his old spunky self again."
— Patch's Mom
⭐⭐⭐⭐⭐
"My 12-year-old cat Leo was diagnosed with HCM 4 months ago. Dr. Kevin gave me confidence to try rapamycin. He is now breathing much better — and his arthritis improved too. 6 weeks on rapamycin."
— Leo's Owner
Is Rapamycin Right for Your Cat?
Rapamycin is not reserved for cats already in crisis. It works best — and does its greatest good — when started before symptoms steal the time you have left.
|
Rapamycin Is the Right Choice If Your Cat: ✓ Is 6 or older — the age range where HCM, CKD, and cancer risks begin accelerating ✓ Has been diagnosed with HCM, even in early or subclinical stages ✓ Has early kidney changes showing on bloodwork (elevated SDMA, BUN, creatinine trends) ✓ Has chronic inflammation, dental disease, or a history of infection ✓ Is a breed with elevated HCM risk: Maine Coon, Ragdoll, British Shorthair, Persian, Sphynx ✓ Has been diagnosed with cancer — particularly mammary tumors or squamous cell carcinoma ✓ Is currently healthy but belongs to a parent who refuses to wait for the first symptom |
Rapamycin Is Not Just a Product Here. It's a Protocol.
At Helping Pets Live Longer, rapamycin for cats is prescribed within a structured longevity strategy — not handed over and forgotten. Dr. Kevin reviews your cat's heart, kidney, and metabolic health before prescribing. He calibrates the dose to your cat's exact weight. He monitors their response and adjusts over time.
Dosing matters. Timing matters. Monitoring matters. Used correctly, rapamycin can protect years of healthy life. Used without guidance, it may create unnecessary risk.
Inside our Pet Longevity Protocols™, rapamycin is:
• One part of a complete longevity approach
• Dosed for your cat’s specific needs
• Monitored with labs over time
• Reviewed regularly
• Integrated with nutrition, supplements, and blood pressure monitoring
This structure is what makes longevity medicine responsible — and effective for your cat.
Prescription Access
Rapamycin requires a valid veterinary prescription.
You may obtain a prescription in one of two ways:
-
You can email us a precription from your local licensed veterinarian. Here's our email address: HelpingPetsLiveLonger@gmail.com
-
Through a Pet Longevity Strategy Session with Dr. Kevin Toman
The Strategy Session is a medical review of your cat’s history, labs, and risks to determine whether rapamycin is appropriate and safe within a structured Longevity Protocol.
Prescription longevity medications are managed within this system — not separately.
Longevity is not about access. It’s about judgment.
That difference matters.

Important Safety Notes: ✓ Rapamycin is a prescription drug — requires valid veterinary Rx or active HPLL strategy session to order ✓ Not recommended in diabetic cats without veterinary oversight ✓ Rapamycin is degraded by stomach acid — only acid-resistant formulations like HPLL's deliver a therapeutic dose ✓ Beware overseas sources — concentration and purity cannot be verified; trace contaminants have been found by independent labs |
Every month your cat ages without a plan is a month HCM advances unchecked.
You found this page for a reason. You've been looking for something real — not just vitamins and hope, but actual medicine that addresses what's happening in your cat's heart and cells.
Rapamycin is that medicine. Dr. Kevin is ready to prescribe it. The question is whether you act today.

Rapamycin For Cats -- Frequently Asked Questions.
My cat has HCM but no symptoms yet. Should I still start rapamycin?
This is exactly when to start. The Trivium study results — and the entire framework of longevity medicine — support early intervention. Rapamycin stops progression. It cannot reverse damage that has already occurred. Earlier is better.
How is rapamycin given to cats?
One dose, once weekly, given with food. The tablets are small, or you can use our flavored liquid rapamycin. The once-weekly dosing makes compliance manageable even for the most stubborn cats.
Can rapamycin be combined with Felycin-CA1?
Felycin-CA1 is the FDA conditionally-approved brand name form of sirolimus (rapamycin) — the same active ingredient in HPLL's compounded rapamycin for cats. Dr. Kevin will guide you on whether generic rapamycin, Felycin-CA1, or a combination approach is right for your cat's specific situation.
Will rapamycin interact with my cat's other medications?
All drug interactions are reviewed during your Longevity Strategy Session or when your vet submits a prescription. Certain cardiac medications and supplements require evaluation. This is part of why active veterinary oversight is built into every HPLL rapamycin prescription.
