Both front legs were twisted to some degree, she limped and occasionally bit at her front legs. Oral glucosamine, chondroitin and msm supplements did nothing. My vet, who also happened to be a friend told me about Adequan, an injectable Form of glucosamine used in horses and dogs. I did lots of research on this, even contacting the company and talking to them. For no good reason, they had done only extremely limited testing on cats and at the time had no plans to conduct more even though they found no adverse results. I decided to give it a try and it made a HUGE difference! Eventually I gave her the shots at home whenever I noticed her limping increase, which was about every 2 weeks. As she aged, I gradually had to give the injections more frequently, about once a week. The bad part was it was an injection in the muscle, which I did not like to do, even though my cat did not seem to mind much. My cat has since died (17 years) but I would definitely consider this medication again if arthritis was an issue for any of my cats.Osteoarthritis is a common, but under-recognized condition in senior cats.
