It helped my 17-year-old cat so much. She moves far better and hops back onto the sofa again. Already bought it a second time.

A little daily joint support goes a long way for senior cats.
STEPHANIE HEINZ (VETERINARIAN)
My cat loves the taste. He seems to be moving better - chasing the other two more often!
My older cats absolutely love the flavor and it seems to be helping with their stiff joints. I already subscribed - love this stuff.
Helps so much and tastes good. After just 5 days my cat climbed back over the ladder - something he hadn't done in over a year!
My cat couldn't get onto the chair anymore, and little by little she's climbing up again. Honestly a great product.
Glucosamine
A natural building block of cartilage, glucosamine helps maintain the smooth, cushioning tissue and joint fluid that let your cat jump, climb and stretch with ease.
Green-Lipped Mussel
Our headline joint active — a whole-food source of natural omega-3s and cartilage glycosaminoglycans that supports joint comfort, flexibility and a healthy inflammatory response.
Chondroitin Sulfate
A core component of healthy cartilage and joint fluid, chondroitin works alongside glucosamine to help keep joints cushioned, lubricated and moving smoothly.
Manganese
An essential trace mineral that acts as a cofactor in the body's own building of cartilage and connective tissue — quietly supporting the structures that keep your cat mobile.
Vitamin E
A protective antioxidant that helps shield your cat's cells and connective tissue from everyday oxidative stress, and keeps the omega-3 oils in the formula fresh.
Salmon Oil
Rich in omega-3 EPA & DHA, salmon oil supports joint comfort and a balanced inflammatory response — the omega-3s shown in cats to support easier movement and activity.

From our veterinarian
A vet's take on feline joint care
Many cat owners ask me the same thing: is my cat just slowing down with age - or is it her joints?
It's often in that moment that you feel a little helpless - and that's exactly where good daily care makes the difference.
Joints are working structures under constant load. Glucosamine and chondroitin sulfate help maintain healthy cartilage, cushioning and lubrication - supporting comfortable, mobile joints.
Manganese supports normal bone and connective tissue, while omega-3s (EPA & DHA) from salmon oil support a calm inflammatory balance, and vitamin E adds antioxidant cell support.
Best of all, it isn't a daily pill battle but a tasty snack your cat will happily eat - easy to keep up, alongside whatever your own vet recommends.
Owners who support their cat's joints early gain one thing above all: the good feeling of having taken action. That's why I recommend ivvi Hip & Joint.

Stephanie Heinz · Veterinarian
1. Omega-3s and everyday movement in cats
Corbee et al., 2013 – In a double-blind crossover of cats with naturally occurring joint disease, owners reported more activity, easier jumping and stair use, and less stiffness when their cats received fish-oil omega-3s versus a control oil.
2. An EPA/DHA-enriched diet for feline joint comfort
Lefort-Holguin et al., 2024 – A randomized, placebo-controlled study in 30 cats found that a diet enriched with EPA & DHA omega-3s (alongside turmeric and hydrolyzed collagen) improved validated measures of mobility and comfort over 13 weeks.
3. Green-lipped mussel for joint support
Bui & Bierer, 2001 / 2002 – Animals fed whole green-lipped mussel showed significant improvement in joint comfort, swelling and mobility versus placebo, supporting the mussel's role as a natural joint active.
4. A marine green-lipped-mussel extract aids weight-bearing
Vijarnsorn et al., 2019 – In 79 dogs with joint disease, adding a green-lipped-mussel lipid extract (PCSO-524) to standard care supported comfortable weight-bearing over the trial — evidence for the mussel's omega-3s (including ETA) as part of a joint-care routine.
5. Glucosamine + chondroitin for cartilage and mobility
McCarthy et al., 2007 – A randomized double-blind trial showed glucosamine plus chondroitin sulfate significantly improved comfort and weight-bearing, building gradually over the study as the cartilage building blocks took effect.
6. How common joint wear is in cats
Slingerland et al., 2011 / Hardie et al., 2002 – Imaging studies found joint changes in roughly 6 in 10 cats over age 6 — and in the large majority of senior cats — underscoring why early, ongoing mobility support matters even before owners notice slowing down.

Frequently Asked Questions
Everything you need to know about the ingredients, quality, and care behind our award-winning treats.
How much should I give my cat each day?
Just one sachet a day — that's the full daily serving. Each box has 30 sachets for a one-month supply. You can offer it straight from the sachet as a lickable treat or spoon it onto her food; most cats look forward to it once it's part of the daily routine.
How soon will I see a difference?
Joint support is gradual, not instant. The cartilage building blocks and omega-3s work over time, so we recommend giving it daily and being patient — many owners notice their cat moving, jumping or playing a little more freely over a few weeks of consistent use. Every cat is different, so give it a fair, steady run before you judge it.
What if my cat is picky and won't eat it?
This is where the creamy, real-tuna formula shines — most fussy and senior cats happily lick it right up, and palatability is the thing owners rave about most. That said, we'll be honest: no single flavor wins over every cat. If yours turns up her nose, our 90-day money-back guarantee means you can try it completely risk-free.
Is it safe? Are there any cautions?
It's a clean, vet-formulated daily supplement, but introduce it gradually so your cat's stomach can adjust, especially if she has a sensitive tummy. Because it contains green-lipped mussel (a shellfish), avoid it if your cat has a known shellfish sensitivity, and always check with your veterinarian first if she's pregnant, nursing, or on any medication.
Can I give it alongside my vet's joint medication or Solensia?
Many owners use it as a daily, food-based complement to their vet's care. Because it's a supplement rather than a medication, it's generally meant to sit alongside — not replace — treatments your vet has prescribed. We always recommend giving your veterinarian a quick heads-up so they can confirm it fits your cat's specific plan.
What's actually in it, and how clean is it?
A triple-action joint blend of green-lipped mussel, glucosamine and chondroitin, plus salmon oil omega-3s (EPA & DHA), vitamin E, manganese and vitamin C — all in a base of real tuna. No meat by-products, no artificial flavors, and no artificial colors, so it's a treat you can feel good about giving her every single day.
What's your return policy?
Every order is backed by our 90-day money-back guarantee. Give it an honest try, and if you or your cat aren't happy for any reason, just reach out and we'll make it right — no hassle. That way the only thing you have to lose is watching her struggle to make the jump.
