If you feel like someone is always watching you, you're probably just paranoid. Or, you could be like this family who learned they were watching TV and a mountain lion was just outside their window doing the same.
I think I found scientific proof that skunks are at the top of the food chain. I've seen bears attack wolves, mountain lions, elk and bison and win just about every time. I've never seen a bear successfully take down a skunk including this big guy that got schooled.
If you've never heard a mountain lion scream while camping and/or hunting in the wild, you're missing out. Wait. Maybe you're not. A Wyoming hunter shared blood-curdling cat screams he heard while hunting something else and the responses are hysterical.
When you go hunting, you hope you'll run into a big buck. You also understand that seeing a mountain lion is a possibility. It's not common though to see both animals in a mortal battle which is what some Colorado hunters witnessed recently.
