this site, by a non-hunting resident of Colorado, lists alleged lion attacks.. It also has other assorted cougar "facts"

I don't know much about it, but it could be a useful reference/starting point for info on these sorts of things:

Anyone intersted in this stuff should read "Stalked by a Mountain Lion" Pretty informative book about lion behavior. Was surprised at some things and the reasoning behind them. I will definatly keep a closer eye on my children after reading this book.
