Finally a supplement my cat will eat!
By LoisaidasMom on Jan 3, 2021
I'm the proud furparent of a very cute, but finicky tripod wonder cat. Our vet has for years told us to look into supplements to keep her joints strong, specially since she puts more strain on her one back leg for balance (which of course also affects her hips). For a long time we used cosequin powdered capsules mixed in her food but after a while I think Her Highness caught on to our trickery so we wanted to opt more for a treat-like supplement instead. Thus, we've gone through countless different brands of supplement chews only to have Demon Diva deny them all. This one she finally likes! She actually gets excited when I open the bag and will look at me for more when she's finished with her I'm the proud furparent of a very cute, but finicky tripod wonder cat.

Anywho, I always feel reviews based on finicky felines' tastes are unfair, so I'm not knocking other brands that might work for your cat, but ours seems to like this one (at least for now lol). It's all a crapshoot with cats anyway and we literally landed on these through trial and error. Ahhhh, cats! Gotta love 'em! … more

anything but Chewy
By Schnooks on Dec 29, 2020
I am sure that these would be very good, except for the fact that pets cannot swallow them. They are not at all soft or chewy. They are hard and break into sawdust like food once bitten into. One pet was actually choking on it and the others coughed it out. They can be smashed and be sprinkled into wet food...and I would not have cared if the package had said that and was prepared to spend the time doing that.

Seems to Taste Great
By AnaC on Jan 13, 2021
My cat seems to like the way these taste as he always lines up to get them. I’m giving them to him as a preventative measure so I can’t attest to how well they actually do work, like if he had arthritis or anything. He’s 18 lbs so I wanted to get him started on something early (he’s two) while we work on getting him to his ideal 15 lbs.

My cat wouldn't eat these
By KCats on Jan 3, 2021
I've tried this brand before with other supplements, but it seems cats don't like the chews. I don't know if it's the size, the strong smell, or the texture. Two of our three cats wouldn't eat them. Of course, the cat who didn't need them did.

She loves it!
By LauraK on Jan 2, 2021
So we have a 16 & 1/2 year old cat. She is doing very well but has some arthritis. She really loves these treats. Hopefully they get her moving a little easier. Time will tell but she does enjoy them!

This literally made my arthritic cat walk and jump again. :O
By Saintlunatic on Aug 22, 2020
I tried Everything from the vet for 3 years, my cat Aurora suffered from terrible arthritis in rear leg. She was not over weight. She limped and could not jump up on any of the furniture or beds in the cat rooms where the other cats were. She slept in a small pet bed on floor. I tried horrible steroids and other scary meds vets prescribed and they made her sick and did nothing for her limp. I finally bought these GlycoFlex treats on chewy. and within 2 months she was not limping and within 4 months she was jumping up on her big cat condo and other high cat furniture and I didn't have to give these to her since. She never limped again in her last 5 years of life. She passed just this week 8/17 I tried Everything from the vet for 3 years, my cat Aurora suffered from terrible arthritis in rear leg.

I recommended these to my sister for her dog 2 years ago with similar joint issues and her dog is doing great after a few months. If you hate giving your pets scary meds with horrible side effects that are also expensive, give these a try. I was really amazed at how well my cat got so fast and was able to enjoy her life again without being in horrible pain. Wish I'd know about these sooner. … more

Cat Didn't Like Them
By Allie on Nov 29, 2020
I'm sure these are perfectly acceptable treats, but unfortunately, my cat would not deign to eat them, so I guess we'll never know.

He likes it!
By drakes on Nov 18, 2020
Finally found a joint supplement my cat likes. We are halfway through the bag, so it may be too soon to tell if it is helping. Nevertheless we are trying!

Great treat
By CatMom on Sep 16, 2020
I have tried several products in an attempt to help my older cats with their joint health. They have turned their nose up every time. This product was recommended by their vet and they both love it. Also I have noticed a difference in their activity level so it’s working.

Arthritic Cat
By Jules on Dec 1, 2020
This helped incredibly with my 14 year old cat’s arthritis. It’s almost as if he’s a new cat!
