You are either feeding the wrong food, feeding them to much, (feeding the bowl and not the cat) they could have hairballs, even if they are short haired because all cats are shedding now. You need to elevate your food bowls, feed in small amounts and make sure that water is around the food for the cats. If the cat continues to throw up then for goodness sake take it to another vet, especially if you have tried the ideas to get it to stop.
These boards, as Xastion has said, are geared towards specific concerns. Although all of us love cats, some people don't even go to the lounge anymore, not enough time, but they will go to the specific forums where their expertise lies and try to help those with questions and concerns. If you have a health concern, it usually is a major deal, so we try and get to those forums first to help out. The lounge is just for fun stuff, feel good stuff and prayer requests etc. You won't lose track of your posts, because there is always a redirect left letting you know what forum it has been moved to. No moderator that I know of will remove a post completely without leaving a redirect, unless it is a troublesome post left on the boards to create problems or flames.
