If you will look on Cat General you will notice that a lot of us tend to lump all cat related things on that board such as rescue, health and behavior because we know that a large number of members never read anything but CG. In the past I've posted health questions in Cat Health and got one or two responses but then posted it in general and got lots of replies. I think Cat General is just the main and only "catch all" board for many members
I kinda wanted to make this point too. It may not be "proper" but if we want to get replies from the people we know the best, we sometimes have to post it in a place that we KNOW it will get seen.

I try very hard to put health in health and rescue in rescue, but so many people miss them (time restrictions again) that I tend to bend the rules so I can reach the CG lurkers.

Think of it this way: If any threads were meant to exclude certain members then they probably wouldn't have been posted at all, they'd have been PM'd.
