Rated 4.3 out of 5 by 42 reviewers.
Rated 5 out of 5 by Good but not perfect The product is good however the senior kitty who I intended to purchase this for would not eat it. In fact none of my senior kitties would eat this. I think the product is too hard for their teeth. The product is not crunchy however it is twice the size of their normal treats and it is not really really soft so I think the seniors have an issue with it. The younger kitties, 4 years old, have no problem eating them and in fact love them. So, if you have a younger kitty, this is an excellent product for them. However if you have an older kitty or a kitty who has issues with their teeth, this is not for them. October 2, 2016
Rated 4 out of 5 by 2 out of 3 cats agree! My vet recommended these for my oldest cat who tends to overdo it and limp around on occasion. I have 3 cats and all 3 cats ate these without a problem the first 3-4 days, then the oldest cat decided she wasn't that into them. Of course! Now, I can get her to take one very few days if I break it up and beg her a bit. The other 2 cats think they are great. September 20, 2016
Rated 5 out of 5 by The product is great for my cats The product is great for my Cats, they need it too ease their arthritis. I only wish it was not so expensive and if it were sold in a larger quantity. September 25, 2016
Rated 4 out of 5 by One out of two cats liked them. My picky cat likes them, but my cat that usually eats everything won't touch them after he ate the first one. September 9, 2016
Rated 1 out of 5 by Product was spoiled Stale and smelly upon arrival, our cat would not eat it. We have been using the product for months from our vet without incident , guess I'll go back to buying it there instead of saving money. September 7, 2016
Rated 5 out of 5 by Cat will eat these I previously gave my elderly cat Vermont Naturals Joint Supplements but she stopped eating those. I switched to these and she eats 1 and 1/2 daily. Added bonus. They have 60, twice as much as VN, and are more cost effective. But most important, cat will eat them. August 16, 2016
Rated 5 out of 5 by Best Joint Supplement for cats My older cat loves the flavor and they work great for her joints. Since she's been taking these she has been more active/playful and runs up and down the stairs like she was a kitten. August 17, 2016
Rated 1 out of 5 by My cats won't touch them I bought this on the recommendation of other cat parents. One said her vet called them 'kitty crack'. They are supposed to be soft chews and they are hard as a rock - could be the product or could be they are old and stale. I have no way of knowing. My cats are elderly and need soft foods. My cats only eat chicken and chicken flavored foods - they took one sniff of these and made kitty 'eww' faces. I tried crumbling them into their regular food and they wouldn't touch their food. So for me, and my cats, these are not good at all and a total waste of money. July 18, 2016
