Mountain Lions in IL?
A friend that I turkey hunt with and ocassionaly deer hunt with has seen a document from the 80's which stated there were 2 pairs of breeding cougars placed in every county to keep deer herds down. 2 pairs means 4 cougars and cougars have more the one cub per litter if you will. over the years that number adds up.
A DNA test showed it was from South Dakota. Everyone thought it must have been someones PET that got out. Most PET Mountain Lions/cougars are captured in South America. Different DNA.
A few weeks before a farmer in Milton WI. seen one in his barn. It cut its paw and left blood and tracks in the snow. The Blood and Cat in Chicago were a match.
My guess is that the cat traveled south on some R&R Tracks from Wisconsin and into the city. I got a call and was there about one hour after it happened. Lots of cops with fancy uniforms, Tv folks, helicopters and city officals. No one believed it.
I bet those cops had to clean their pants.
I, personally have never encountered any sign of a cougar/mountain lion in IL. Who knows.....my patient probably printed the pics off of the internet.
