The Cat HCM Protocol
Your cat has HCM. You want a clear plan, and you want to know whether Felycin is right for your cat.
The Cat HCM Protocol gives you both. Dr. Kevin reviews your cat's echo report, explains what it means, builds a written plan, and, if your cat is a good candidate, starts and monitors Felycin-CA1 with you.
- ✓ An expert review of your cat's echocardiogram within 2 business days
- ✓ A one-on-one Zoom session and a written, stage-specific plan
- ✓ A Felycin evaluation, plus monitored treatment if it fits your cat
- ✓ Guidance from a vet who has treated 400+ cats with HCM
Your Investment of $147 includes:
- Initial Consult
- Custom strategy for your cat's HCM Management
- 3 months of partnership in Your Cat's Care
Does this sound familiar?
- Your vet said "HCM" and handed you a printout. Then you went home and searched for hours.
- You've read about Felycin, but your vet hasn't used it, or isn't sure your cat qualifies.
- You're counting your cat's breaths at night and wondering what's normal.
- You're not sure if your cat is "B1" or "B2," or why it matters.
You're not alone, and you don't have to figure this out by yourself. HCM is the most common heart disease in cats. It affects about 1 in 7 cats, and closer to 1 in 3 cats over age 9.
Why cat parents choose Dr. Kevin
Most general vets see a couple HCM cats a year. Dr. Kevin Toman, DVM, has spent more than 40 years in practice and has treated more than 400 cats with HCM. He is one of the most experienced real-world prescribers of Felycin-CA1 for feline HCM in the US.
That experience shows up in the details:
- which echo findings matter most,
- the dosing of Felycin and other meds,
- drug interactions
- what to watch for in the first months of your kitty's HCM management.
From Dr. Kevin:
I built our Cat HCM Protocol to help cats just like yours fight this progressive disease with comprehensive care and the latest in medications, based upon my 40 years of clinical veterinary experience.
You just won't find this level of support anywhere else, and I'd love to help your cat.

Is your cat a Felycin candidate?
Felycin-CA1 is FDA conditionally approved to manage heart wall thickening in cats with subclinical HCM, meaning the heart wall is thick but the cat has no signs of heart failure.
Your cat may be a candidate for Felycin-CA1 if:
- ☐ An echocardiogram shows HCM
- ☐ You don't want to "watch and wait"
- ☐ You can do follow-up bloodwork and rechecks
What Felycin does, and what it doesn't
We believe you should see the evidence clearly before you decide.
| Question | What we know | Evidence |
|---|---|---|
| Is it FDA approved for cats? | Yes. Conditionally approved in March 2025, the first drug approved for HCM in cats. | Proven |
| Does it target the thickening itself? | Yes. In a trial, it stopped the heart wall from getting thicker over 6 months in cats with early HCM. | Proven |
| Is it well tolerated? | Side effects were similar to placebo in the trial. Monitoring is still needed. | Proven |
| Does it help cats live longer? | Not yet known. A larger study is under way. | Unproven |
| Is it a cure? | No. Felycin is generally thought to be a lifetime medication that can slow/stop HCM progression. | Proven |
Felycin must be monitored closely in cats with liver disease or diabetes. It is prescription-only and, like every other medication, does not work for all patients.
. Dr. Kevin prescribes it only when your cat's case supports it. Read the full Felycin guide →
What does it cost, all in?
No surprises. Here's the full picture.
| Item | Cost | Notes |
|---|---|---|
| The Cat HCM Protocol | $147 | One time enrollment for Dr. Kevin's assessment, your cat's custom plan, and 3 months of partnership. |
| Felycin-CA1 (if prescribed) | From $8 to 27 USD per week, depending on your cat's weight | Weekly tablet. Cost depends on your cat's weight. |
| Bloodwork before and during treatment | Through your local vet | Liver values and blood sugar |
| Follow-up echocardiograms | Through your local vet | Usually every 6–12 months, by stage |
For perspective: a single emergency visit for heart failure or a blood clot will cost you more than a year of this protocol.
What cat parents are saying:
"Having lost one Sphynx already to HCM, the last thing I'd want to live through is another loss like this. Dr. Kevin organized *everything* we needed to get Felycin-CA for our new family members who regrettably are also HCM Stage I. Fast, reliable, and honest that's Dr. Kevin & his team." -- Chris P.
"Real understanding of our needs and outstanding communication!! Thank you for existing there to help us all over the world, to find solutions not accesible to us and to help us reaching them!"-- Claudiu
"Great Service!! Extraordinarily grateful to Dr. K and HPLL. My boy Milo takes the pill like a champ, and we feel so much relief. We really appreciate the outreach from Dr. K and his team--especially the original consult and then the speedy shipment of Felycin."

Frequently asked questions
Do I need an echocardiogram before I enroll?
It helps a lot. If your cat doesn't have one yet, we'll explain exactly what to ask your vet for, and you can send it when it's ready.
Is Felycin included in the $147?
No. The protocol covers Dr. Kevin's review, session, plan and support. If Felycin is prescribed, the medication is a separate cost that depends on your cat's weight.
Will my cat definitely get Felycin?
No. Felycin is prescribed only when it's medically right for your cat. Many cats are good candidates, but some cats may need a different plan. Dr. Kevin will work with you to create the best solution for your cat in all cases.
Do I still need my local vet?
Yes. Your local vet does the hands-on care: exams, bloodwork and ultrasounds. Dr. Kevin works alongside them and shares a written plan.
How fast will I hear back?
You'll get your case review in about 2 business days after we receive your cat's records.
Is Felycin safe for cats?
In the approval trial, side effects were similar to placebo. Like any prescription drug, it needs monitoring, which is built into the protocol.
My cat already has heart failure. Can you help?
Yes. Dr. Kevin can still review your cat's case and build a plan around the treatments that fit.
Your next step
Your cat's heart is changing whether or not you act. The best time to build a plan is before a crisis.
