Support Your Cat’s Healthy Aging and Heart Function — the Smart Way

Aging does not slow down.

Inflammation builds quietly.
Organ function declines before signs appear.
Many cats show heart or kidney stress long before you see symptoms.

Rapamycin is one of the most studied medications in longevity medicine for cats — especially for HCM, inflammation, kidney support, and cancer risk.

Research suggests that rapamycin may help:

• Support normal heart function in cats with HCM
• Reduce inflammation linked to aging
• Support kidney function over time
• Lower cancer risk and slow progression of age-related changes

The earlier aging pathways are addressed, the greater the opportunity to protect healthy years.  

Rapamycin Works Best Inside a Structured Longevity Plan

Rapamycin is not a supplement.

It is a powerful prescription medication that affects core aging biology — including pathways involved in heart disease, inflammation, and cell repair.

That means:

   • Dose matters
   • Timing matters
   • Monitoring matters
   • Your cat’s heart, kidney, and metabolic health matter

Used correctly, rapamycin can support long-term health.  Used without guidance, rapamycin may create unneeded risks for your cat.

Inside the Pet Longevity Protocol™, 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:

  1. You can email us a precription from your local licensed veterinarian.  Here's our email address:  HelpingPetsLiveLonger@gmail.com

  2. 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.

Is Now The Right Time?

Rapamycin may be appropriate for:

   • Cats age 8 and older
   • Cats diagnosed with or showing signs of HCM
   • Cats with early kidney changes (elevated SDMA, CKD)
   • Cats with chronic inflammation or cancer risk
   • Pet Parents who want to intervene before major decline

Longevity medicine works best when started before decline accelerates.

Let's be honest.  Waiting rarely improves biology.

Before You Purchase

Rapamycin delivers its greatest benefit when used inside a structured medical plan.

If you have not yet completed a Pet Longevity Strategy Session, we recommend starting there to ensure proper dosing, monitoring, and long-term oversight.

If you already have a prescription and are currently enrolled in a Longevity Protocol, you are welcome to order above.

Healthy Years Are Built Early.

Every month your cat ages without a plan is a month aging continues unchecked.

Build the strategy now — so you’re not wishing you had later.

Why Us?

Many providers can write a prescription.  Few understand structured longevity medicine.

At Helping Pets Live Longer, rapamycin is not treated as a product.

It is part of a monitored strategy built on:

• 40+ years of clinical experience
• Data-guided drug dosing management
• Heart, kidney, and inflammation tracking
• Ongoing adjustment as your cat ages

Longevity is not about access.

It’s about judgment.

That difference matters.

What is rapamycin for cats?

Rapamycin is a drug meant to prolong the life of your pet, and it provides several health benefits we’ll get into soon. However, since rapamycin is kind of a new kid on the block, we first want to share what you should know about rapamycin:

  • Rapamycin is a medicine to make cats live longer and not a supplement. It can only be obtained with a prescription from your vet OR after a consultation with me!
  • Rapamycin is currently an off-label drug, but that doesn’t mean that it isn’t trusted in the veterinary community.
  • Our rapamycin is 99.946% pure, and you can see those test results here.  Beware of purchasing rapamycin from overseas, as you don’t know the concentration or the purity. Other groups have found both trace lead and trace benzene in rapamycin sourced from overseas, and this kind of negates the benefit of a longevity drug, yes? 

If you want a really in-depth look at what rapamycin is, learn more here.

Common problems that rapamycin addresses in cats

Rapamycin can be used for the following health issues in cats:

  • The big news is that the recent Trivium study showed that rapamycin can stop the progression of hypertrophic cardiomyopathy (HCM) in cats. Up until rapamycin, there has never been an effective way to treat this fatal heart disease in cats.  
  • Rapamycin has been proven to help slow the progression of chronic kidney disease (CKD) in other mammals, including humans. There are clinical trials for rapamycin and CKD in cats going on at Ohio State, Florida, and Texas veterinary schools
  • Rapamycin has been proven beneficial in cat mammary cancer and squamous cell carcinomas of the skin.
  • Rapamycin has been shown to be a safe way of increasing lifespan in every mammalian species studied to date.  

FAQs about rapamycin for cats

The Trivium study showed that rapamycin is very safe for use in cats, with no more side effects seen in the cats treated with rapamycin than the cats treated with a placebo.  

The new treatment for HCM in cats is rapamycin, and we are currently the only online source for prescription veterinary rapamycin. Rapamycin is the only drug ever shown to prevent the progression of fatal HCM in cats, which is very exciting. The Trivium study showed that rapamycin is both effective and safe in treating hypertrophic cardiomyopathy in cats. 

Along with rapamycin, the four best ways to help your cat live longer are…

  • Yearly anesthetic dentals with x-rays of every tooth to prevent periodontal disease, which has been shown to reduce lifespan by up to 15%
  • Keeping them at a healthy weight to avoid diabetes
  • Doing what you can to prevent kidney disease with the dentals above, check your cat’s blood pressure, and do an annual urinalysis on them
  • Avoid vaccines unless your cat is at risk for the disease

Although there are no longevity biomarkers currently known in any species, including humans, our goals in treating your cat with rapamycin are to stop the progression of fatal hypertrophic cardiomyopathy, to maintain their comfort, and to minimize the risks of both cancer and CKD. 

The cons of rapamycin are simply the need for weekly oral administration and its cost. Rapamycin has been shown to be a very safe drug in cats, dogs, and other mammals.

Rapamycin is a prescription drug which means that you cannot buy Rapamycin online without consulting a certified veterinarian. I recommend either obtaining a prescription from your local veterinarian/cardiologist or scheduling a concierge consult with Dr. Kevin before ordering the rapamycin for your cat.

Absolutely. If you’re curious to learn more about the medical rationale behind how rapamycin for cats works and whether it’s the right choice for your cat or anything else about your pet’s health, then you may contact me directly at ktomandvm@gmail.com. Simple questions are easy, and we can set up a consult if things get more complex.

Visible improvements to our cat's health!

So grateful Dr. Kevin's kindness and support in educating us and making Rapamycin available to our early HCM kitty. We first did the consult, which was so thorough and informative in capturing details about our cat. Our kitty has been on rapamycin since Dec 2025 (about 2 months) and along with following Dr. Kevin's diet & dental suggestions, our kitty is NOTICEABLY more active energetic, playful and overall happier. Working with Dr. Kevin has been the best investment in our little bud's happiness and ours too.

Leo Mainecoon mix with HCM

My 12 year cat Leo was diagnosed with HCM 4 months ago. Dr Kevin gave me confidence to try Rapamyacin even though Leo is diabetic. Careful monitoring of his blood sugar levels which did not increase. He is now breathing much better and in remission from his diabetes. 6 weeks on Rapamyacin. Leo has a great appetite and plenty of energy for a 12 year old cat. Very happy with the service that Dr Kevin provides. I can't thank him enough for the help he has given us and hope for this terrible disease. Thank you so much!

Thank you, Dr. Kevin

The sad fact is that HCM is a terrible diagnosis, and the standard approach doesn't offer much hope for keeping our beloved furry friends going for long. Enter rapamycin and Dr. Kevin. Everyone considering getting rapacmycin for their pet should understand that nothing is guaranteed, but it does offer a reason for hope, which is otherwise in short supply. So thank you, thank you, thank you Dr. Kevin for your careful evaluation of our little guy's medical records and for making rapamycin available. We greatly appreciate that you were able to respond to our urgent request in a timely way.
