Most kidney supplements for cats get one thing wrong: the AIM Lock. Every cat's AIM cleanup protein is handcuffed from birth, so dead-cell debris quietly clogs the kidney filters for years.
That's why Mendara built a Cleanup Crew Formula with L-Cystine, L-Methionine and Taurine, paired with yeast beta-glucans and astragalus root. The amino acids fuel the sulfur road the cleanup runs on. The beta-glucans wake the cleanup crew. Up to 75% of kidney function is gone before bloodwork shows it.
Every scoop delivers a vet-formulated dose of what aging kidneys need to clear debris and stay strong before the silence breaks.

Yes. Mendara is made with gentle, natural ingredients in a GMP-certified facility and is third-party lab tested for purity and potency. No artificial fillers, no synthetic preservatives, no fluff.
Amino acids, astragalus and beta-glucans in a bonito base are gentle on cats of all sizes and breeds. However, if your cat is pregnant, nursing, or on prescription meds, we recommend checking with your vet before starting any new supplement, just to be safe.
How long until I see results?
Most cats show noticeable improvement within 2 to 4 weeks of daily use, especially in energy, appetite, and coat shine, with better kidney numbers at the next vet checkup. Some cats respond sooner, but consistent daily use is essential for full results.
What's the correct dosage and how do I give it?
Use the scoop in the tub, dosed by your cat's weight: ½ scoop under 7 lbs, 1 scoop for 7–16 lbs, 2 scoops for 17 lbs and over. Sprinkle it on wet or dry food once a day. No pills, no fights.
How is this better than renal diets or taurine?
Renal diets lower the kidney's workload and plain taurine is just one stop on the road. Neither one clears the debris. Mendara's Cleanup Crew Formula targets the AIM Lock itself so the debris gets flagged and hauled away. Plus, no fillers, no fake flavors, no waste.
Are there any side effects?
Mendara is well-tolerated by most cats. A small number may have a mild tummy upset when first starting. Start with a pinch and build up over a week, and give it with food. If your cat is on prescription medication or has a chronic health condition, check with your vet before starting.
Is it safe for kittens and senior cats?
Yes. Mendara is formulated for cats of all ages, sizes, and breeds. Senior cats benefit most from daily AIM support as their kidneys age. Kittens can start from 12 weeks old.
What makes Mendara different?
While most kidney products are generic blends or low-dose treats your cat won't touch, Mendara is built on AIM research, vet formulated, and uses 5 actives with doses on the label in a bonito base cats actually eat. Every batch is third-party lab tested. No fillers, no fluff. Just real results.
Every ingredient in Mendara is there for a reason. Delivered in a freeze-dried bonito powder your cat will actually eat, not leave in the bowl. We don't hide behind generic kidney blends, fillers, or vague "renal complexes." You get a transparent list of vet-formulated ingredients, each dosed at a meaningful level and built to support your cat's kidneys.

Most cat kidney supplements sound the same. But there are critical differences in how they're made, dosed, and given that decide whether your cat actually gets the benefit. Here's why ours stands out:
Most kidney supplements toss in a few vitamins and hope. None of them touch the real problem: the AIM Lock that keeps your cat's cleanup protein handcuffed from birth while debris clogs the filters. Mendara starts there. Our Cleanup Crew Formula feeds the exact pathway the cleanup runs on, so your cat's kidneys get help clearing debris every day, long before bloodwork would ever show a problem.
We don't hide behind vague labels. Every scoop contains 150mg of L-Cystine and 100mg of L-Methionine for the sulfur road the cleanup runs on, 50mg of Taurine for kidney cell support, 50mg of Astragalus and 50mg of Yeast Beta-Glucans to wake the cleanup crew, all in a freeze-dried wild-caught bonito base made in the USA. No fillers. No mystery blends. Just the actives that actually do the work, dosed at meaningful levels.
The best supplement in the world does nothing if your cat refuses to eat it. We've heard the same story from hundreds of cat parents: "$40 bag of renal treats went straight in the trash." Mendara solves that. Just sprinkle one scoop over her food and the bonito powder disappears into the meal. No forcing, no battles, no wasted product. Even cats who turn their nose up at treats and pastes take Mendara without noticing it's there.
"My tabby Oliver is 14 and had stopped jumping on the bed. After 3 weeks on Mendara he's racing down the hall at night and even jumped on the counter yesterday for the first time in months."
"My picky Siamese Cleo refused every kidney treat I bought. With Mendara I just sprinkle a scoop on her food and she eats it without noticing. Finally a supplement I can actually get into her every day."
"We tried the fountain, the renal diet, plain taurine, you name it. Six weeks on Mendara and Milo's kidney numbers came back better at his checkup. Something in this one is actually working."
"I was a skeptic until I read the Miyazaki paper on the AIM Lock. Two months on Mendara and my girl Luna greets me at the door again. Her coat shines and her appetite is back."
Giving your cat Mendara is simple, mess-free, and built to fit into your daily routine, even with picky eaters.
