Why AIM Matters:
The silent condition responsible for kidney failure in 1 in 3 cats worldwide.
Why AIM Matters:
The silent condition responsible for kidney failure in 1 in 3 cats worldwide.
Failing Kidneys
Every cat's kidney depends on a specific protein to clear dead-cell debris from its filtering tubes. In every domestic cat, that protein is permanently bound and unable to work — debris accumulates silently from birth until the filters fail.
No Warning Signs
Cats are hardwired to mask pain and illness until it is severe. Most owners notice nothing until their cat has already lost the majority of their kidney function — permanently.
Irreversible Damage
Kidney cells do not regenerate. Every year without support is another year of silent, cumulative damage that cannot be undone — no matter how good the diet or how attentive the care.
The Leading Cause of Death in Cats
1 in 3 cats develops chronic kidney disease. It is the single biggest reason cats die before their time.
The Discovery That Changed Everything We Know About Cats
In 2016, a Japanese immunologist named Dr. Toru Miyazaki published findings in Nature Medicine that proved every domestic cat carries a condition no other mammal on earth shares — a protein their kidneys depend on that has never been able to function.
Feleria AIM is built on the amino-acid science his research identified — giving your cat's kidneys the daily nutritional support that pathway has always been missing.

""I'm a vet tech so I went into this completely skeptical. I read the actual Miyazaki paper myself. The IgM binding data is real — I checked. I looked at every ingredient and the logic is sound. No fillers, no proprietary blends, doses you can actually see on the label. That alone put it ahead of everything else I'd looked at. Miso has been on it five months. Her energy is better than it was a year ago — she's 7 and acting like she's 3. My senior vet actually asked what I was doing differently at her last visit. Coming from him that's basically a standing ovation. I'll never not have this in the house.""

""Pepper has been with me through everything. Divorce, moving four times, the worst years of my life. She's 10 now and I think about losing her more than I'd ever admit to anyone. Found Feleria AIM doing research one night when I couldn't sleep — read about the Miyazaki discovery and honestly had to sit with it for a minute. Every cat. From birth. Nobody ever told us this. She's been on it six months and I don't know how to explain the difference except that she seems more present. More herself. Jumps up on the bed again at 3am like she used to. My vet said her kidneys look great for her age. I'm not spending every night quietly dreading the future anymore. I'm just glad she's here.""

""I've had cats my whole life. Lost four of them to kidney failure over the years — always the same story, seemed fine and then they weren't. My daughter found this for me after I got Biscuit, a 7 year old rescue. She said mum you're not going through that again. I'll be honest I was skeptical, I'm not one for supplements. But I read about the Japanese research and it made sense to me — more sense than anything a vet had ever told me about why it keeps happening. Biscuit has been on it eight months. Eats every last bit of his bowl, jumps up onto the bed at night, sits on my lap every evening while I watch television. My vet said his kidneys look perfect. At 71 I know how precious time is. I'm not taking a single morning with him for granted.""

""Lost Mochi to kidney failure at 9. She seemed completely fine and then she wasn't — four months later she was gone. Got Luna two years later and I swore I wasn't going through that again. She's been on feleria AIM since day one. She's 4 now, tears around the apartment at midnight, sits on my face every morning, won't leave me alone. Her last bloodwork was perfect. I don't dread the vet anymore. I actually look forward to it.""

Proven Benefits. Backed by Vet Science.
Offsets the natural decline that comes with every passing year.
Taurine synthesis naturally declines as dogs age — and with it, the body's ability to protect cells from oxidative damage. Daily supplementation gives your dog's body what it can no longer produce on its own.
- Protects cells from the oxidative damage that drives premature aging
- Supports brain health & sustained energy through every life stage
Regulated immune response and reduced cellular inflammation.
Taurine acts as a direct antioxidant inside immune cells, neutralising the free radicals that drive chronic inflammation. It keeps your dog's immune system calibrated to fight back without overreacting.
- Neutralises free radicals at the cellular level
- Supports faster recovery and year-round immune resilience
The amino acid your dog's heart depends on most.
Taurine controls calcium movement inside cardiac cells — the mechanism behind every heartbeat. When levels drop, the heart muscle silently weakens and the chambers begin to dilate.
- Helps prevent the muscle thinning and chamber dilation associated with DCM
- The single most critical amino acid for long-term canine heart function
Supports healthy vision and prevents haziness.
The retina holds a higher concentration of taurine than almost any other tissue in the body. When levels fall, photoreceptor cells deteriorate — gradually, silently, and often irreversibly.
- Protects retinal cells from oxidative stress and age-related damage
- Deficiency is a leading nutritional cause of progressive vision loss in dogs
Is Feleria Right for Your Cat?
See if your cat is at risk:
Senior Cat
+
Taurine synthesis naturally declines with age. The older your dog gets, the less their body produces on its own — and the more their heart, eyes, and immune system depend on adequate levels. Seniors need it most.
My Cat Seems Healthy
+
That's exactly when to start. Taurine deficiency is completely silent — no symptoms, no warning signs — until the heart is already under serious stress. By the time something looks wrong, the deficiency has been building for months.
At-Risk Breed
+
Golden Retrievers, Cocker Spaniels, Newfoundlands, Dobermans, Great Danes and Labrador Retrievers all have a documented predisposition to taurine-deficient heart disease. For these breeds, supplementation isn't optional — it's responsible ownership.
Grain-Free Diet
+
This is the highest risk factor we know of. Grain-free diets are consistently linked to lower taurine levels in dogs — it's the reason the FDA launched a full investigation. If your dog is eating grain-free, they need this.

"Kidney failure is the most common reason I lose cat patients too soon. The amino-acid science behind why it happens is now clear — and Feleria AIM is the only supplement I've found that actually addresses it, with every ingredient and dose right there on the label."

How is this different from other kidney supplements?+
+
