These keep the kitten in an older cat
January 31, 2021
If your older cat likes these treats, they can make a big difference. Our 16 year-old fellow had visibly advancing arthritis. After being on these treats for maybe a month, the improvement was amazing. He is much less stiff and notably more enthusiastic to run and play. It's joyful to see him that way. In consultation with our vet, he gets a large dose: 2 in the morning and 2 at night. It's a bit pricey, yet for us it's worth it. The price at Entirely Pets was reasonable.
As in humans, glucosamine doesn't help everyone, yet it does help some. Our other older cat won't touch these treats.

Merchant Response:Thank you for the wonderful review Jill
  • Very visible decrease in stiffness and visible effects of arthritis.
  • Happier, more active cat.
  • Not all cats like the taste.
  • They don't help all cats.
  • Not cheap.

for my cat's arthritis
September 23, 2020
My cat limps because of his arthritis. This product helps, but doesn't completely stop the limp. He doesn't like the taste, but he didn't like any of the other brands I tried either. I continue to buy it because it seems to work better than any of the others. It's worth a try since my cat is so picky about taste

Merchant Response:Hi Kathy, glad you have found some relief. For more ideas you could give our customer service a call.
  • Seems to help him
  • Taste

My 16 year old cat was having trouble jumping onto my sofa, chair, bed, etc. due to joint pain. After taking Glyco Flex daily for a week he has resumed his jumping. He is a much happier kitty!!! Plus he enjoys eating the chew. He won't eat any of the powder or crystal products when I add them to his food.

Glycoflex for cats has certainly helped two of my rescued felines enjoy a better quality of life. They both suffer from arthritic pain but after a couple of weeks of taking Glycoflex, they are able to run around a bit and resume their previous rascal ways!

Best affordable solution for aging cat
June 3, 2015
My cat had had years of untreated arthritis (normal for a declawed cat) and was walking slowly, limping and clearly in pain when we got her. We heard about the green lipped mussel ingredient from the vet and did some research as the recommended products were ridiculously priced. I found this product that was still relatively cheaper (I'm in Canada and need to consider USD conversion and shipping). We started with a month of 2x daily and decreased to once daily with her meal and she loves the treat and is running everywhere now! I cut the large chew into 3 or 4 pieces so they're easier to chew and digest. It has been a miracle medication for her and would recommend it to all cat owners who are concerned about the joint health of their cat and want to give them freedom to do what they want without pain.

I received the same product from my Vet's office but it was less expensive by ordering through Entirely Pets. Same product, different price and delivered to my home!

Cat likes Glyco Flex
August 28, 2014
I have a 19 year old cat that liked the Glyco Flex twice a day. He has lately had difficulty chewing it so I ground it up into his food now. It does help his arthritis.

My cats are fussy as ever but liked the Glyco Flex II chews. I tried the Glyco Flex III and 3 out of 4 cats did not like these. Flavor I suppose but chew slightly larger as well. Will not buy again.

I've been giving one tablet twice a day to my 14 yr old tortie for a few weeks now. She seems to complain less when I touch her hips.

Questions and Answers

1 Question & 1 Answer
from Mentor, OH asked:
November 5, 2014
my vet suggested I use Glyco-Flex III Feline for my 14 year old cat.. I would like to purchase a refill of this product from entirely pets. Upon comparing the active ingredients on my package from my vet and your product, the first five or so active ingredients are the same, but the package from the vet has about five more ingredients that are not listed in your product. Also, the package from my vet is not the same as your package. although they are both made by Vetri-Science. Can you tell me if this is the identical product?
1 Answer
Was the original product the tablet form of Glyco-Flex III? This is the soft chew version, which includes less ingredients than the tablet version. Additionally, Vetri-Science recently changed the packaging of this line of products, so it may look different- but the ingredients should be the same. You can find the tablet version below:
