    Glyco Flex for Cats
    As soon as she tried these tablets and the treats, my 18 year old cat started playing like a kitten again (shorter lived). I sprinkle it in her food and see the effects everyday. Her joints were popping when she walked and that is what prompted the purchase of this product. She can sneak up on me again!! We are both happy with this product (and the treat version too.)

    Helps increase mobility and activity
    We have a two year old tabby who had FHO surgery on his left hip at 13 months. After all the rehab and healing was over I felt he still wasn't moving around quite like such a young cat should. He would hesitate a lot before jumping or running. He's been taking Glyco Flex I for a few months now and he seems less painful and is much more active! Watching him you wouldn't know he had FHO surgery. Plus he loves the tablets plain, no need to put them in a pill pocket!

    Product has helped our kitty!
    One of our cats is 18 years old and has trouble getting around, due to discomfort in his hind quarters. This product has improved his mobility a lot!

    Cats love them.
    My cats gobble these up. Seems to be helping older cats somewhat....little more energy or easier to move around maybe. They are not to point where they need glyco flex II.
