Joint Strong is not a medication, just a supplement. Which is not to say that she could not have a reaction to it... any life form can develop a reaction to anything at any time, really. I am not super familiar with the metacam, but do know that most anything NSAID can cause GI issues.
I found that Tig had zero problems with it once we got past that initial adjustment, but... I also learned a month or two later that the same company makes a supplement called "Young At Heart" which I decided to try Tig on. It contains the glucosamine but not at as high a level as the JS. (Tig was hit by a car as a pup, and so has old trauma in the pelvic area...) The distributor I was talking to that day worked it out to half a scoop of the JS and 3/4 scoop of the Young At Heart. That caused an improvement in her digestion over what it was both before and after starting the JS, with the absence of nightly er... "off-gassing" and also a general increase in perkiness, and that remains the supplementation she's on now.
I had her on fish oil and sam-e before, but she's getting plenty of EFAs from the other, and the sam-e did not seem needed, so I don't do that now. We ran blood on her at the beginning of this month, and while her BUN is still a little high, the other things that were a little high (cholesterol, creatinine and a liver thing) last year are within normal ranges. So I'm pretty happy with her progress, since at her age (11) one usually doesn't expect to see things improving.
So that may be one route. The guy behind all this stuff is a bodybuilding supplementation expert by the name of Bob Fritz, I want to say. I've heard that a person might get hold of him by calling the 800 number on the can... never tried it... and get his perspective on things.
One might also consider that if she's a little out of whack, a few days of acidophilus/bifidus supplementation could be helpful. Enzymes can also be helpful, and I note in looking at the Young At Heart that that formula has both items, which I probably knew at some other time but I'm falling asleep here so had forgotten. But that would explain the GI benefits.
And now I will go to bed as soon as possible, as I have a carload of (not so happy with me!) feral cats that need an early morning lift down to Burbank to get some snippage done.
