I saw a one on my farm in southern Jefferson Co. last fall while bush hogging a field. It was a youngster; I could tell by the size and the coloring. I spoke with MDC but they had zero interest in coming out. That fall I found 13 dead deer on my property, none near water, so no blue tounge. One had it's back cut up. I asked MDC if they wanted to come out and confirm it but they declined.
I've spent almost my entire career working outdoors in British Columbia, Montana, Wyoming, Nevada, New Mexico, and Arizona. I know what a cougar is when I see one. They have watched me working, stalked me while I was elk hunting, and I have sat and watched them in the desert with a spotting scope. My local agent who has been helping me with restoring the quail population believed me and asked the MDC cougar expert to come out. She pointed out my experience with them, the deer carcass that they could look at, and the hair I found in a barbwire fence. No interest. The boss said the last time he went out, it turned out to be a 40lb. red tabby cat.... Another guy said he believed that maybe it could have been a cougar traveling through but "doubted it". He said it was possible that young males were coming down the Missouri River corridor and expanding their range. I mentioned that I believed there was a breeding female out at the farm and all interest from MDC immediately went away. I believe they don't want to acknowledge them.....
