Anyway, I wanted to post this as an idea for others. I had a cat who was 18 years old who effectively cured his own arthritis. He was a very smart little fellow, and he had terrible arthritis that had caused such spots on his hip that were so hot to touch, and he'd limp around in pain. The glucosamine did help some, but nothing worked until we purchased a dehumidifier for our basement. This little tuxedo cat sat next to this dehumidifier day and night, for about a month or more. At the time, I thought he was doing it because of the heat. Low and behold, about a month after doing this, his arthritis was healed, his weight had dropped dramatically, and he was pouncing around like a little kitten. No more hot joints.
I have arthritis, and have thought about trying it, but I don't have the time to sit next to that thing all day. Ahhh the life of a cat... My best friend Snapper has gone to his reward... And may have found a cure of arthritis for some... Hope this helps.
