Put my first cat to sleep at 11. “Quality of life,” they said, and I believed them — he’d stopped jumping, stopped playing, slept all day. It took me years to learn that almost everything on that list was treatable joint pain. Not age. Pain. That broke me all over again. Adopted Biscuit at six and started Purrfect his first week home, because I am never doing that again. He’s eight now and honestly acts younger than the day I got him. Does laps around the apartment at 3am like a kitten, clears the counter in one jump like it’s nothing. He doesn’t even know it’s a supplement. It goes on his food and he cleans the bowl. I have never once had to trick him. My vet can’t believe he’s eight. For the first time I actually believe he’s going to grow old with me. I just wish someone had told me when it could still have saved my first.

One daily scoop to help protect your cat’s joints for years to come.

What’s inside Purrfect?

Here is what goes into each 2 g scoop.

Active ingredients per scoop

  • Fish Oil Powder (EPA + DHA)1,000 mg

    300 mg of EPA and DHA, the two omega-3s that work alongside ETA to keep her joints calm.

  • Green-Lipped Mussel Powder (ETA)300 mg

    The only food on earth that carries ETA, the fat her body stopped making around age 3.

  • Micronized PEA150 mg

    Eases joint pain while the omega-3s do their work, and micronized so her body absorbs it better.

For taste and freshness

  • Poultry Liver Hydrolysate500 mg

    The taste that makes her clean the bowl.

  • Vitamin E Powder20 mg
    Rosemary Extract10 mg

    Two antioxidants that keep the omega-3s fresh in the jar.

Other ingredient: silicon dioxide, 20 mg. Contains fish, mollusk and poultry.

Why does my cat need joint support?

ETA is a fat every cat is born making. Its only job is to calm her joints after every jump, before the damage builds up.

Until about 3, her body makes plenty. After 3, it stops making enough. Every cat. From that day, her joints are never fully calmed again, and the damage quietly adds up.

That’s why “quality of life” is the number one reason cats are put to sleep. Behind those words, it’s almost always arthritis. 6 out of 10 cats over the age of 6 have it, and 8 out of 10 by the time they are 8, regardless of breed, weight, or how well you care for them.

No senior food, no salmon oil and no glucosamine puts it back. None of them contains ETA.

Purrfect delivers ETA from the only food on earth that carries it, the New Zealand green-lipped mussel, with a poultry liver taste your cat will actually want to eat.

What results will my cat actually see?

Within the first few weeks, most cat parents see her jump without thinking twice, play longer and groom all the way down her back again.

That happens because every scoop gives her joints ETA, the fat her body stopped making around age 3, which no food or joint chew contains.

By the third month, she moves like a much younger cat, and she keeps it for the years ahead.

You get your kitty back, and you get more time with her.

Can my cat have it every day? Will she eat it?

Yes, every day. Purrfect is made to be given month after month. Your cat should be 12 months or older.

Poultry liver gives each scoop its taste. You mix it into her food, and it becomes part of her meal. There are no pills to give.

#1
The reason cats are put to sleep.

  • Cartilage Wears Down

    After age 3, your cat’s body stops making ETA. Nothing calms his joints anymore. Jump after jump, his cartilage wears away.

  • Hidden Pain

    Cats are masters at hiding pain. They rarely limp. They just jump less.

  • Hard to Repair

    Cartilage heals very poorly. The wear adds up over the years. The best time to protect your cat’s cartilage is before it wears down.

  • The Leading Cause of Death in Cats

    85% of cat deaths in the U.S. are euthanasia, and the reason given is almost always "quality of life," which in most cases means a cat whose arthritis has become too painful.

Why Joint Pain Rarely Shows Up at the Vet

The early signs are small things your cat does at home. She jumps onto the couch a little less. She avoids the litter box. She hides more and plays less.

An exam room has no couch to jump on, no litter box to avoid, and no toy to ignore. Most of these signs cannot happen there. So the clinic rarely sees them.

There is no blood test for pain. An X-ray only shows the damage once it’s done. And at the clinic, she hides her pain.

You don’t need to see a sign to start Purrfect.

Juniper, 10 years old
Juniper · 10 yrsVerified Buyer

“Juniper is 10 and has been with me through a lot (divorce, three moves, all of it). I started googling why she quit jumping on the dresser one night because I was spiraling honestly and found Purrfect. Read that 60% of cats have arthritis by age 6 and kind of couldn't believe nobody talks about this. Like she's 10 so she's probably had this for years and I thought it was just age?? Started her on it maybe 5 months ago. She took to it right away which surprised me because she's picky about everything. I don't want to overstate it but she's back up on the dresser and grooming her back end again which my vet said is actually a good sign. Last checkup he said she's moving well for her age. The main thing is I just feel like I'm actually doing something instead of just watching her get old. That probably sounds dramatic for a powder but if you know you know.”

Miso, 7 years old
Miso · 7 yrsVerified Buyer

“I'm a vet tech so I went into this completely skeptical. I read their study myself, 52 cats over two months, and I looked up the research on omega-3 and green-lipped mussel in cats. It's real, I checked. I looked at every ingredient and the logic is sound. Three actives, no proprietary blend, 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 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.”

Walter, 7 years old
Walter · 7 yrsVerified Buyer

“I've had cats my whole life. Watched four of them slow right down in their last years, always the same story, stopped jumping, hid under the bed, and we all said that's just age. My daughter found Purrfect for me after I got Walter, 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 how cats hide pain and it made sense to me, more sense than anything I'd ever read about why they all end up like that. Walter 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 hips and knees feel good. At 71 I know how precious time is. I'm not taking a single morning with him for granted.”

Maple, 4 years old
Maple · 4 yrsVerified Buyer

“Watched Tilly go stiff at 10. She seemed fine and then she wasn't, stopped jumping, and by the time anyone said arthritis the damage was done. Got Maple two years later and I swore I wasn't waiting this time. She's been on Purrfect since I brought her home at 2. She's 4 now, tears around the apartment at midnight, sits on my face every morning, won't leave me alone. Her last checkup was perfect. I don't dread the vet anymore. I look forward to it.”

Theo, 5 years old
Theo · 5 yrsVerified Buyer

“Had an orthopedic bed, a heated pad, steps up to the couch because I read it helps with joints. Thought I had it covered. Milo was living on the floor by 12 anyway, vet showed me the x-ray. He'd seemed completely fine a year before. Read up on it after and it all made sense. Nobody ever told me a soft bed doesn't stop what's wearing down inside the joint. Got Theo last year, started Purrfect immediately. He's the most active cat I've ever had. His six month checkup was perfect. I wish I'd known this with Milo.”

Cleo, 6 years old
Cleo · 6 yrsVerified Buyer

“Cleo was 6. Six years old. Perfectly healthy at her annual in March. By October she'd stopped using the litter box and couldn't get up on the couch. Arthritis. Both sides. I had done everything, the good food, the checkups, the expensive stuff. I thought I was one of the good ones. I didn't sleep properly for a week after. The first thing I did was research everything I possibly could. Found Purrfect and ordered before I even finished reading. Cleo has been on it since that week. She's back to being herself. 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 day with her for granted.”

Hazel, 2 years old
Hazel · 2 yrsVerified Buyer

“Olive got diagnosed with arthritis at 12. Perfect checkup in March, could barely get on the bed by September. I kept replaying everything, was she jumping less and I missed it? Was she grooming less? I convinced myself I'd just not been paying attention. Hazel came along eight months later, two years old, and I was watching her like a hawk every single day. Every time she took the stairs a bit slow my stomach dropped. Found Purrfect 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.”

Purrfect™ Mussel Supplement
Birdie, 5 years old
Birdie · 5 yrsVerified Buyer

“I had her on fish oil from a pump, a joint chew, senior food, because I read it helped with joints. Thought I had it handled. Peaches was done jumping by 11 anyway, fine one month, hiding under the bed the next. Got Birdie last year and found Purrfect doing research. Learned that the oil was only ever one piece of it, and liquid goes off once it's open anyway. Nine months in. Birdie races up the stairs at midnight, waits outside the bathroom for me, purrs the second I sit down. I don't dread her getting older anymore. I've got a plan for it.”

What Purrfect Does

Aging well starts with healthy joints.

When your cat’s joints hurt, she starts to do less. Little by little, her quality of life slips. A daily scoop supports her joints along the way.

  • More healthy years
  • Better quality of life

Calmer joints, day after day.

Every scoop pairs omega-3 from fish oil with micronized PEA. Both help calm the pain in her joints.

  • Defends her joints
  • Supports easier movement

Made to look after her cartilage.

Once cartilage wears down, it rarely grows back. Each scoop has green-lipped mussel to support it.

  • Minimizes cartilage wear and tear
  • Helps keep her cartilage healthy

Energy for the things she loves.

If your cat seems to sleep more, it can look like aging. She’s not sleeping more. She’s moving less. Comfortable joints make it easier to play.

  • Supports her energy, day to day
  • Helps maintain mobility

Is Purrfect Right for Your Cat?

Find the answer that fits your cat.

My Cat Seems Healthy

That’s exactly when to start. Most cats have joint pain long before they show it. One scoop a day supports her joints before the wear shows.

Senior Cat

Starting now is better than waiting. Her joints keep wearing down in the meantime. Every scoop supports the cartilage she still has.

Already on a Joint Supplement or Vet Treatment

You don’t have to choose. Purrfect can be added to what she already takes. Show the ingredient list to her vet before her first scoop.

My Vet Hasn’t Mentioned This

The first signs show up at home, not at the clinic. They are small changes. Her vet may not have seen them yet.

I Already Give Glucosamine and Senior Food

Senior food is a good choice for an older cat, and we’d never tell you otherwise. But like glucosamine, it doesn’t contain ETA, the fat her body stopped making around age 3, and no kibble or joint chew can put that back. Purrfect does.

Arthritis is the most common reason I lose cat patients too soon. The research on omega-3s from green-lipped mussel is now clear, and Purrfect is the only supplement I've found that delivers them at a real dose, with every ingredient right there on the label.

Questions? We Have Answers.

Does Purrfect actually work?

Each daily scoop helps calm joint pain and support cartilage health.

Even if your cat shows no signs yet, it helps protect her joints for the years ahead.

How do I give it to my cat?

Mix it into your cat’s food, once a day. The amount depends on her weight.

Daily amount by weight

  • Under 7 lbs½ scoop
  • 7 to 16 lbs1 scoop
  • Over 16 lbs2 scoops
Is it safe for daily use?

Yes. You can give it every day, month after month. Your cat can start once she is 12 months old.

It contains fish, mollusk and poultry. If she has a food allergy or takes medication, ask your vet before you start.

When will I see results?

Most cat parents notice more play and easier jumps within the first few weeks, and the deeper joint protection keeps building over 90 days.

Can I give it with other supplements?

Yes. It can be given alongside your cat’s other supplements. If you are unsure, check with your vet.

How is Purrfect different from other joint supplements?

It combines omega-3, green-lipped mussel and micronized PEA in one scoop. Many joint supplements are designed for dogs. Purrfect is dosed for a cat.

How long does one jar last?

One month, at one scoop a day. Each jar holds 60 g, or 30 scoops.

Smaller and larger cats use a different amount. See the amount by weight 

How long does it keep?

Purrfect has a 2-year shelf life.
