Customer Reviews

Rated 3.9 out of 5 by 33 reviewers.
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 5 out of 5 by Picky indoor cat & semi-feral outdoor cat approved! This Glycoflex chew and the Dentalife kibbles (4) are the first items our 14yo indoor cat and 12yo outdoor cat eat! They SELECT them FIRST from among their dry food kibbles! We recently began giving our aging girls these two new additions to their daily diet because of mobility & dental plaque issues. This may not seem like it is special nor unusual, BUT bear in mind that BOTH CATS are used to grain-free Chicken and grain-free Seafood high-protein dry cat food blended 50-50... not some corn/grain-filler byproduct-meal food from the grocery store!

Rated 5 out of 5 by Product is great My neutered male cat has cistitis. This product keeps it under control. Not its original purpose perhaps, but the vet tech happened to know it works for this, too. Thank goodness, because kitty was peeing in the sink and bathtub, which I found out is what they tend to do with that condition. October 11, 2016
Rated 2 out of 5 by My cats hated them and refused to even eat one. This product probably works, and some cats may like them, but none of my three cats would touch them. October 8, 2016
Rated 5 out of 5 by All the right stuff in this for my old, stiff cat. and she likes it. My cat currently likes this product. I have tried two other feline glucosamine chewables. She liked the pet Naturals one for several bags and then stopped. She wouldn't touch the next one I tried. The Glycoflex is a little hard for her (she has no teeth) but i warm it in the microwave for 8 seconds and she loves it. Hope her desire lasts! September 26, 2016
Rated 5 out of 5 by Cat loved them! They are a little big and chewy. My cat started having issues with arthritis. She is 15 years old. I worried she was ending her life spam. She was cleaning herself. It has only been a week and she if feeling better! Starting to clean herself again.. September 9, 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
