During the past two decades a variety of over-the-counter dietary supplements called nutraceuticals mostly glucosamine, chondroitin sulfate and omega-3 fatty acids have gained popularity for their ability to ease the joint discomfort associated with feline arthritis. Glucosamine and chondroitin additives might help in improving the joints of cats. These amino sugars are natural building blocks of the cartilage in the joints. Since, osteoarthritis is caused by the breakdown of cartilage, the remaining cartilage would theoretically be improved by supplementing the animal’s diet with these cartilage builders. But, glucosamine and chondroitin don’t do that, since damaged cartilage can’t be rebuilt. If a product actually contains, what the supplier says it contains, then the safety level is pretty high.
Omega-3 fatty acids are dietary supplements, since they have anti-inflammatory effects and may be effective in easing joint discomfort caused by osteoarthritis. Supplements containing these fatty acids obtained from the tissues of mackerel, salmon, trout and several other types of fish improve joint health and mobility. Glucosamine and chondroitin are safe, although they can possibly have gastrointestinal side effects. As for fish oil, lower doses of high-quality products are quite well tolerated, with mild gastrointestinal side effects being most common. With higher doses of fish oil, however, there is the possibility of bleeding problems, immunosuppression and several other side effects.
There are studies in other animals and anecdotal reports indicating that these substances may improve comfort in some situations perhaps due to an anti-inflammatory mechanism. But it’s really important to discuss with your veterinarian and make sure that you select a high-quality product before feeding the supplement to your cat.
