      Cats will not eat - even the outdoor cat

      from Yakima WA on 5/27/2019
      These chews are quite large - about the size of a large multi-vitamin - so if you are buying this for an older cat like I did, the chew is too big for the majority of cats to chew . My older kitty still has all of her teeth but many older cats may be missing teeth or have sore teeth. I tried splitting the chew into segments and she will still have none of it. I tried to feed the chews to an older outdoor kitty who eats almost anything put in front of him, and he will not eat these either. A waste of $10.


      I liked the IDEA of a supplement that might help my older kitty with back/hip joint pain.


      Chews are sized far too large and their flavor/odor does not tempt the cat to want to eat. For these reasons alone this item should be returnable after opening.

      Works great for my 18 year old cat

      from RALEIGH NC on 5/06/2019
      She has arthritis in her hips and this product has helped her immensely, she's getting around better and doesn't seem to have as much discomfort.


      Easy to administer, and my cat likes it.


      It's a little crumbly toward the bottom of the package.

    • More than a treat, with GLmussel extract

      from Long Island, New York on 2/13/2018
      I don't know if I'm imagining this but since giving my 11-year old boy cat (who is quite arthritic , tending to lethargy, and somewhat obese) these Glyco-Flex II Chews by Vetri-Science Laboratories, about 4-6 per day in divided doses, he seems to be more energetic, mobile and alert I'm into my 2nd bag and almost finished with that.


      I think the green-lipped mussel extract powder has been effective for my cat's inflamation, but this is a guess, because the other ingredients seem also quite good, such as glucosamine and grape seed extract.


      Nothing thus far.

    • Great Products and Prices

      from Seattle, WA on 12/28/2014
      Glyco-Flex II Feline by Vetri-Science Laboratories is a great product and provides relief to our Molly.


      Great product and super pricing.


      New packaging. Hoping this is the same product we have ordered previously.

    • My Pomeranian thinks they are treats

      from Outter Banks, NC on 12/15/2014
      On vet orders, my Pomeranian will take these for life. without them he is lame in one leg. Glyo-Flex II by Vetri-Science Laboratories has eliminated this, now Chipper can walk in comfort.


      Taste good, soft chews, my Pomeranian loves them!


      Package must be sealed properly to avoid product from getting stale/hard.

    • Tasty And Better Yet...They Work!!

      from Bremerton, WA on 9/21/2014
      I started using these in August 2014 for my 16 year old orange tabby Marmalade, at my vet's recommendation. The cat loves them and his stiff front legs have loosened up quite noticeably. He's getting around much better now, which is more than I can say for my 66 year old body! Be sure to administer after your cat has eaten, as directions say. The one time I didn't do that, Marmalade threw it back up.


      Taste good and they apparently work!


      Nothing, except maybe would prefer a lower price. But I already saved $2.00 a package over what my vet charges...and you get free shipping right to your door.

      Seems to help and cats love them

      from Cupertino, CA on 2/16/2013
      Glyco-Flex II Feline contains ingredients that sound useful and my 13-year-old cats seem to have fewer agility problems. They certainly love to eat the chews!

      This product has made my old cats life

      from Ohio on 2/12/2013
      My 16 yr. old cat had really slowed down. He was walking so stiff legged that he barely bent his knee. After about 6 weeks of taking Glyco-Flex II Feline as directed I started noticing him getting around much better. He even started jumping up to places hes abandoned. Theres no doubt hes still an older cat but these chews have definitely improved his quality of life.


      My cat likes them as much as any treat.


      If the bag is not closed perfectly they get very hard very quickly.

      Another hit with my cat

      from Northridge, CA on 12/08/2012
      My cat loves these chicken-liver flavored chews which are moist and succulent (from a cats POV!). These chews have many added ingredients missing from the typical glucosamine-chondoitrin tabs/powders/wafers etc on the market (such as MSM DMG Mussel rich in Amino acids) and make Glyco-Flex II Feline an extra-healthy supplement for the kitty. So far we are happy with Glyco-Flex II Feline as is our cat.


      Yummy and packed with good ingredients.


      None so far.
