I promised that I would update you on the Cosequin so here it is.
I tend to switch and eat from Obidian's bowl also, but I still eat a good amount form my bowl also. While it does alter the taste of my stinky goodness a little, it is not bad enough to where I refuse to eat it. I just finish what Obsidian leaves first because it tastes better and besides if I don't than Jackie might beat me to it.
Before Bob started giving it to me in my food I had a noticeable limp, and I didn't jump up onto things very much. Now the limp is mostly gone and I have started jumping into Bob's lap or onto his desk instead of asking him to pick me up, so that is a real good thing.
