Nadia K.

Lost my first cat to kidney problems at 8. Vet said it's just what happens with cats but watching her go from healthy to gone in six weeks destroyed me. Adopted Mochi from a rescue at six and started AIM the same week because I wasn't doing that again. She's seven now and honestly she acts younger than when I got her. Eats like I've been starving her, does laps at 3am like a kitten, still curls into me every night. She doesn't even know it's a supplement. My vet can't believe she's seven. For the first time I actually think she's going to grow old with me. I just wish I'd found this before I lost my first.

Why does my cat need AIM support?

AIM is a protein every mammal is born with. Its only job is to clear dead-cell debris from the kidneys before it builds up and causes damage.

In dogs and humans it works fine. In cats it doesn't. Every domestic cat carries a genetic defect that prevents their AIM from ever fully activating, which means cellular waste has been quietly accumulating in their kidneys since the day they were born.

That's why kidney disease is the number one killer of cats and why 1 in 3 will develop it regardless of diet, breed, or how well you care for them. No fountain, no wet food, and no standard supplement touches this.

Sepili AIM delivers the specific amino acids and immune triggers the kidney's cleanup process depends on, in a pure tuna bonito base your cat will actually want to eat.

The Science Behind It

Thinning and shedding start at the follicle, not the surface — so Hair Helper Spray works where it counts. Biotin strengthens strands, Sophora Flavescens helps balance the scalp conditions tied to thinning, Ginger boosts circulation to the roots, and Rice Water nourishes hair from within. Just 2–3 sprays, twice a day — for fuller, thicker hair in as little as 8 weeks.

What results will my cat actually see?

Every cat's kidneys accumulate dead-cell debris from birth — a genetic defect that no food or fountain can fix.

Sepili AIM supplies the exact amino-acid complex that kidney cleanup process depends on, supporting healthier kidney function before damage becomes irreversible.

Cats who start early show cleaner kidney panels, stronger energy levels, and healthier coats — and hold onto them well into old age.

The scariest part of kidney disease is how silent it is. This is what you do about it before the silence breaks.

Is it safe for daily use — and will my cat actually eat it?

Absolutely. Every ingredient in Sepili AIM is safe for daily use with no side effects — your cat's body simply uses what it needs and clears the rest.

Sepili AIM contains pure freeze-dried bonito (dried flake tuna).

The supplement your cat was never going to touch becomes the thing they sprint to their bowl for. No pills. No fights. No hiding it in anything.

Just one scoop in their food every morning — the easiest decision you'll make for their health.

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.

Sepili 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.

"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 Sepili 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'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."

"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 Sepili 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."

Verified Buyer

Amanda,34

"Had three fountains in the house, all wet food, added taurine because I read it helps with kidneys. Thought I had it covered. Lost Biscuit at 11 anyway — vet said kidney failure. He'd seemed completely fine three months before. Found the Miyazaki research after and it all made sense. Nobody ever told me hydration doesn't stop what's actually building inside them. Got Archie last year, started Sepili AIM immediately. He's the healthiest cat I've ever had. His six month checkup was perfect. I wish I'd known this with Biscuit."

Verified Buyer

Chris,38

"Cleo was 5. Five years old. Perfectly healthy at her annual in March. By October she was gone. Kidney failure. I had done everything — two fountains, exclusively wet food, the expensive stuff. I thought I was one of the good ones. I wasn't sleeping properly for a year after. Got Rosie six months ago and the first thing I did was research everything I possibly could. Found Sepili AIM and ordered before I even finished reading. Rosie has been on it since week one. She's the most energetic cat I've ever had. Sprints down the hallway at 2am, sits outside the shower waiting for me, purrs so loud I can hear her from the other room. I don't take a single morning with her for granted."

Verified Buyer

Linda,57

"Lost Olive at 10. Perfect checkup in March, gone by September. I kept replaying everything — was she drinking more and I missed it? Was she sleeping more? I convinced myself I'd just not been paying attention. Got Hazel eight months later and I was watching her like a hawk every single day. Every time she left food in her bowl my stomach dropped. Found the Miyazaki research at 2am, read everything, ordered before I went to sleep. Hazel has been on it seven months. Flies around the house, sleeps on my chest, yells at me the second my alarm goes off. Her first checkup came back completely clear. I'm not spending every day quietly terrified anymore. I'm just present with her."

Verified Buyer

Nancy,43

"I had two fountains, fed all wet food, added taurine because I read it helped with kidneys. Thought I had it handled. Lost Pumpkin at 8 anyway — eating normally one week, gone the next. Got Clover last year and found Sepili AIM doing research. Learned that taurine was never built for kidney health — it doesn't touch the part that actually matters. Nine months in. Clover sprints down the hallway at midnight, sits outside the bathroom waiting for me, purrs loud enough to hear from the other room. I don't dread her checkups anymore. I look forward to them."

Aging Longevity
Kidney Support
Immune Resilience
Renal Defense

Offsets the natural decline that comes with every passing year.

Cats who receive consistent daily nutritional support give their kidneys the best possible chance of functioning well into old age. Cleaner bloodwork. More energy. A cat that stays sharp and active long past the age most owners quietly start to worry.

Supports healthy kidney function into senior years

Promotes energy coat health and overall vitality

Supports the kidney's natural ability to clear cellular debris.

Every cat's kidney filtering tubes depend on a precise amino-acid complex to stay clear. Without it, dead-cell debris accumulates silently from birth — scarring the filters and reducing function year after year. Sepili AIM supplies L-Cystine and L-Methionine in the exact ratio that process depends on, giving the kidney what it needs to do its job.

Supports the kidney's natural debris-clearing process daily

Targets the root problem not just the symptoms

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 cat's immune system calibrated to fight back without overreacting.

Neutralises free radicals at the cellular level

Supports faster recovery and year-round immune resilience

Protects kidney cells from the damage that accumulates with age.

L-Methionine and Astragalus work at the cellular level to protect kidney tissue from the oxidative stress that accelerates scarring. Without this protection, the damage that builds silently from birth compounds faster with every passing year.

Protects kidney tissue from oxidative damage and scarring

Supports cellular resilience through every life stage

Is Sepili Right for Your Cat?

See if your cat is at risk:

My Cat Seems Healthy

That's exactly when to start. The condition builds silently from birth — long before any symptoms appear. By the time a vet detects a problem, most cats have already lost 65–75% of kidney function permanently. The cats who do best are the ones whose owners started before anything looked wrong.

Senior Cat

The damage is cumulative. Every year without nutritional support is another year of silent buildup that cannot be undone. Senior cats are the most urgent case — but starting now is still better than not starting.

Already on a Kidney Supplement

Most kidney supplements address general support. Sepili AIM targets the specific amino-acid pathway behind the condition Dr. Miyazaki's research identified. It's not either/or — it's the part most supplements don't touch.

My Vet Hasn't Mentioned This

Most vets only test kidney health after symptoms appear. By then, the deficiency has already done permanent damage.

Sepili is preventative — it fills the gap before your vet ever needs to have that conversation with you.

I Already Use Taurine and a Water Fountain

Both reduce the strain on your cat's kidneys — and we'd never tell you otherwise. But hydration alone doesn't address why 1 in 3 cats still develops kidney disease. That's a condition no diet or water intake can reach. Sepili AIM does.

Got Questions? We've Got Answers!

Does AIM supplementation actually work?

Absolutely. Cats who start daily supplementation early and stay consistent give their kidneys the best possible chance of functioning well into old age. Cleaner bloodwork. More healthy years. A cat that stays active and present long past the age most owners start to worry.

My cat is already older — is it too late?

It's not too late — but it matters that you start now. Kidney damage is cumulative and irreversible, which means the goal at any age is to slow what's building and support what's left.

Senior cats are actually the most urgent case. The best time to start was years ago. The second best time is today.

When will I see results?

Most cat parents notice improved energy and engagement within the first few weeks. The deeper kidney-level support builds over 90 days.

How is this different from other kidney supplements?

Most kidney supplements address general support or symptom management. Sepili AIM is the only US-made supplement built on the amino-acid science behind Dr. Miyazaki's Nature Medicine research — targeting the condition at its root, not just the surface.

How long does one tub last?

One tub contains 60 servings. For cats under 7 lbs, that's two months. For cats between 7–16 lbs, one month. Most parents subscribe monthly and save 30%.

How do I give it to my cat?

Sprinkle directly over your cat's wet food, dry kibble, or raw meal once daily. Under 7 lbs: 1/2 Scoop Daily (1g)
7 lbs to 16 lbs: 1 Scoop Daily (2g)
Over 17 lbs: 2 Scoops Daily (4g)

Is it safe for daily use?

Completely safe for daily use at any age with no side effects. Every ingredient is vet-formulated, third-party tested, and manufactured in the USA. Your cat's body uses what it needs and clears the rest naturally.

Can it be taken alongside medications or other supplements?

Yes. Sepili AIM is a safe daily nutritional supplement with no known interactions.

I already give my cat taurine, do I still need this?

Taurine supports your cat's heart and eyes — it's essential and we include it in our formula too. But taurine is the end of the sulfur-amino pathway. The kidney's natural cleanup process needs what's at the beginning of it. That's what Sepili AIM supplies — the part taurine was never built to reach.
