Shark cartilage is a potent source of collagen, glucosamine and chondroitin sulphates which help support joint and connective tissue health. The marine cartilage powder used in O2B Feline Plus tablets is manufactured from non-endangered school and rig shark species harvested from New Zealand fisheries that operate a world class quota management system. Marine cartilage has over 40% pure collagen protein, plus essential and non-essential amino acids, which are necessary for elasticity of the tissues, natural healing of skin, ligaments and tendons. Marine cartilage is also a good source of minerals particularly calcium, phosphorous, magnesium, potassium, zinc, iron, chromium, manganese and silica. These components are essential for the maintenance and normal function of cells, muscles, bones and joints.


Greenshell™ Mussel (GSM) is a rich natural source of chondroitin, glucosamine and omega 3 essential fatty acids. All three of these compounds are needed to maintain and rebuild healthy connective tissues such as cartilage, tendons and ligaments. GSM is an effective and natural bio-active ingredient that promotes overall animal health commonly associated with mobility, healthy skin, bones and teeth, circulatory and immune systems. The Greenshell™ Mussel we use in O2B Feline Plus are harvested from the pristine NZ marine environment.


As a sea vegetable, Kelp contains 46 minerals, 16 amino acids (the building blocks of protein) and 11 different vitamins. A dense source of vitamins A, B1, B2, B3, C, D and E, as well as minerals including zinc, iodine, magnesium, iron, potassium, copper and calcium. Kelp contains the highest natural concentration of calcium of any food – 10 times more than milk. There are many reasons to supplement your cat with Kelp but key reasons include support for digestion, metabolism and cellular energy production. New Zealand harvested kelp is believed to be one of the most nutrient dense vegetables on the planet.


Brewer’s Yeast is a fantastic source of B Vitamins specifically Folic acid, B12, Thiamin, Niacin and is packed full of minerals including Chromium, Potassium and Zinc to support healthy skin, eyes and coat. It also contains high levels of amino acids and is a good source of protein.

Vitamin B1 (Thiamine HCl)

Thiamine is essential nutrient for the overall good health of cats as it converts carbohydrates into energy to power the neurological system and support the cardiovascular system.


Vitamin C supports the strength and maintenance of connective tissue in the body, including in bones and teeth, gums and all mucosal membranes. Vitamin C is vital for the function of the immune system and assists with the absorption and utilisation of iron.

  1. Highly Recommend

    Review by Robyn Anderson (verified owner)

    I have a 14 1/2 year old cat has bad arthritis. I thought we were at the beginning of the end and he we were trying some heavy pain meds from vet which had him completely zonked out. I didn’t like what that was doing to him so took him off those and kept him on his Metacam and his monthly Arthropen injections and started using these supplements alongside and he is his old self again. He’s still slow, but so much better. Highly recommend.

  2. A new lease on life for my cat.

    Review by Bronwyn (verified owner)

    My cat was unable to jump onto the sofa or bed due to his arthritis. After a week on this supplement I weaned him of his pain meds. A month in, he can jump again (onto the bench!), he is moving freely and generally much happier.

  3. Great for arthritis

    Review by Crystal

    These worked great for my cat for arthritis she was previously on vet prescribed medication that didn’t help but now she’s jumping on the couch without her step and seems more happy and able

  4. They have made a noticeable difference !!!!

    Review by Alex

    I was skeptical about what this would do for our cats when a friend recommended these. I did a month on/month off to see the effect. These are not miracle anti-ageing wonder tablets, but they absolutely have made an improvement to the cats mobility and vitality. The other cat won;t eat them unless they are masked in cat biscuit flavour. He doesn’t know what he’s missing out on !!!!

  5. My cat changed within a week!

    Review by Julie of Richmond

    After visiting the vet, paying large bills to try and help my old cat with an arthritis problem and changing diet but not a lot of improvement, I heard about this product and my cat changed within a week.
    No more crying or pain when trying to jump high…she is nearly 15 and acts like a kitten. No one believes she’s that grand old age and looking so healthy.*
