"Great supplement "
Posted byDanielleon10th Oct 2026I bought this for my 13 year old cat who was starting to show signs of arthritis in his legs. Ive been using it for two weeks and I can see a difference already! Hes a fussy cat! This powder is so easy to add to his dinner. Highly recommend
"Great for cats!"
Posted byOliviaon30th Sep 2026Started both my cats on this after one had a muscle tear and I wanted to start some extra support. They happily eat it straight off the top of their biscuits, and devour it in wet food. The small dose amount helps with the palatability and to be sure they’ve gotten the whole dose. My cat that was sore is no longer limping, and I don’t doubt this product hasn’t helped. Bonus is their coats and extra silky too! Definitely recommend!
"Perfect for seniors"
Posted byMarion16th Sep 2026Both my senior dogs have enjoyed the benefits of Tandem Bone+Joint for quite awhile ago for their arthritis and general wear and tear of their old bodies, and I can say, it is the best way to give your dog (or cat) extra support for their joints and bones. Mixed with some wet food for fussy eaters, its easy to measure correctly without going through several different supplements separately. And it does not smell strongly like green mussel powder sometimes does!
"Both cat and dog love this. "
Posted byKellyon4th Sep 2026We've not long been using this but both pets love the taste. Looking forward to seeing some change in my cat's arthritis symptoms soon. I wish he could tell me if it's helping.
"My cat loves this "
Posted bySarahon10th Aug 2026My fussy senior cat loves this. I add it to a little bit of water to hydrate her biscuits or to her wet meat (so she doesn’t get food boredom).
