Frequently Asked Questions
Yes, any time. No minimum, no cancellation fee. Just reach out and we sort it the same day.
Four drops on their food, once a day. Drop it directly onto whatever they already eat. Most cats eat it without noticing because it tastes like meat. The bowl tells you what you need to know. Most owners see the first change in weeks two to three: a spot they'd stopped claiming, a walk to the food that looks different, a response when you call their name.
60 days. If your cat shows no change after consistent daily use, contact us for a full refund. No forms, no questions. That's it.
Nine active ingredients: Vitamin B1, Vitamin B6, Folic Acid, Vitamin C, Vitamin E, Dong Quai, White Peony Root, Hawthorn Berry, and Liquid Heme Protein. Each one targets a specific stage of blood quality, circulation, and energy. The systems that decline first in a senior cat.
Pills need stomach acid to dissolve. Most senior cats don't make enough, so the pill moves through without breaking down and comes out the other end. The nutrients never reach the blood.
This is a liquid. It absorbs through the soft tissue inside the mouth before the gut is even involved. That's not a workaround. It's the only format that gets through when digestion has slowed down.
Most cats take it without a fight. It tastes like meat.
The Liquid Heme Protein That Skips Their Gut
Energy Recovery
Bypasses Gut
Vet Certified
The first night it goes on their food, watch the bowl. It doesn't need their digestion to work. It absorbs before the gut gets involved. That's the only way this reaches a cat whose stomach acid has declined. That's why the pill never did.

I spent nine months on a ferrous sulfate supplement and saw nothing. When I found out it absorbs at under 5% in cats, I stopped. By week three on this, his appetite was back. He eats it off the dropper. No fight, no hiding it in food.

We adopted Mochi from a rescue. She was thin and flat. Three weeks on this and she started playing. The first time it happened I sat on the floor and watched for a while. I didn't want to move in case she stopped.

Our vet confirmed that most feline iron supplements pass through at under 5% absorption. I switched after that conversation. Oscar has been on this three months. His energy is different. I notice it in the way he moves now, not just in the blood panel.

Rosie is 15. Her digestion has been compromised for two years, so pills were never going to work. Within a week on the liquid her appetite came back. She started purring again. Something she had stopped doing completely. I sent this to three people that same day.

Week two: Biscuit started finishing her meals. Week four: she was in the window. Week six: she hopped onto the sofa on her own. The only thing I changed was the supplement. I didn't know what to expect. I know now.
