I can tell you this, I live in southeast Marion County, and about 12 years ago I saw a large cat up close and it scared me to death. I also know several people that live close by and have told of seeing a large cat within a couple of miles of where I saw it.
I turned into the road that my grandparents and uncles live on(and where we used to hunt) and saw a pair of eyes in the headlights, and as I got closer, I thought it was my uncles German Sheperd dog. I rolled down the window to holler at him and tell him to git home and uh... let me just say it wasn't a dog. It eyes were a bright green, and it had a tail that curved down almost touching the ground and curled back up. I will guarantee you this, there is no automobile in the country that has a power window that can go up faster than when I started cranking the window handle in that old car. The thing made an effortless jump over the fence, and trotted away. I raced to my uncles house to get him to go back with a spotlight, but it was gone when we got back. Several other people that live close by reported seeing a large cat crossing the road, and one reported seeing it very close while bowhunting.
I can also tell you that back then, where I hunted was absolutely swamped with deer. You would see at least 10-12 deer everytime you went in the woods. The opening morning of gun season sounded like World War three, shots everywhere all day long(and this was when it was bucks only and one deer per hunter) but now if you see one or two deer a week you've done good. I went through a six year stretch when I saw 5 deer total (one of those happened to be a decent eight pointer I killed). I can't help but wonder if that cat I saw had/has something to do with it. I never heard of any livestock being killed though, and there are plenty of cows and calfs around. I just don't know. But I do know that whether it be due to the disease that we have nicknamed "blue tongue", or poaching, or the unlimited doe season for the last ten years that finally changed this year, or the infestation of coyotes we have, or the big cat/s like the one I saw, or a combination of all of them, or what, but our deer population has drastically diminished. I saw 7 deer this year total, but this is more than I've seen in the past 5 or six years combined. That used to be a slow mornings hunt.
