Rated 2 out of 5 by Cats won't eat them, treat size too big Product is as described, shipped quickly and arrived within 1-2 days. We had a lot of hopes for this product since our girls are getting on in age and showing signs. 2 main problems: 1) Cats won't eat them... they are not picky eaters either. This seems to be a hit-or-miss point with cats and very polarizing. They either love it or hate it. 2) Too big for most cats. Maine coons would find this bite size (my brother has 2), our siamese couldn't fit them into their mouth. I had to break up the treats into 4 bite-size bits. See attached image - glyco flex treats on right, for size comparison: temptations on left and american quarter in middle. The treats are very dense and square, so they're just as wide as they are tall whereas the temptations are very thin. No results to comment on since they ate half a treat on day one, a quarter of a treat on morning of day 2, and not a single bite on evening of day 2. Will continue to try and update review to reflect any changes if they occur. August 18, 2016
Rated 4 out of 5 by My Cat loves them! It's only been a couple of weeks, but I certainly see my 14 yr old walking around more. He still looks stiff, but at least he's moving. I think the directions recommend 4 weeks so I might be able to upgrade to 5 stars! I'm excited that he loves the taste and there is no work involved in getting him to eat them. I do have them wrapped up in a Ziploc bag as well as the original package. They are not soft, but a bit on the hard side...yet not crunchy. August 18, 2016
Rated 1 out of 5 by Treats My cat that needs them won't eat them, we even tried adding them to cat food. July 29, 2016
Rated 1 out of 5 by Not a hit with the elderly... I tried this product twice as in theory, it sounds perfect for my old Maine Coon's lameness in her hind legs. The treats are move from semi soft to hard in a matter of days and even putting them in a jar, they seem to dry up. My cat was more enthused when I first opened the bag but would not eat them on the third day. I am not sure their yummy factor is high with the felines as my cat will eat anything. May 17, 2016
Rated 4 out of 5 by Seems to Help Mr Kitty! Mr. NP Kitty is about to be 17 human years old, which is something like 85 in cat years. He's about 20 pounds and was in need of some good joint support. He likes these and eats them, which is amazing because he's super picky. So Bravo GlycoFlex! It's hard to tell if it really helps him because he doesn't move like he used to but I can't help but think it does. Subtle changes in behavior for the better. April 8, 2016
Rated 5 out of 5 by Easy to give and effective Both cats 'like' it. There seems to be less joint discomfort, but hard to quantify. I plan to keep them on it! April 15, 2016
Rated 5 out of 5 by Tasty and good for the kitties! Easy to administer and tasty even to the finickiest feline! Packed with goodness - my oldest kitty has been taking it for over 2 months and I can see the sparkle in his eye and perk in his step now, whereas before he was a bit hesitant to jump down or up - he does so now with more ease and confidence. Great product! March 29, 2016
Rated 5 out of 5 by Cat approved! My cat has a luxating patella and arthritis in his right knee. I am so glad I found a glucosamine suppliment that he will eat :) April 1, 2016
