RE: Cougars in Illinois!!
Here we go again. Are they in Il? Or not? I believe they are. Probobly not any kind of a threatening breeding population, just migrants.
But I tell ya. Call the DNR and let them know. I know they are looking for any kind of a good tip that leads them to good solid evidence. If only the bro & sis got some pics! They should definately make good note of that exact tree. If that cat was in it, it had to jump down and leave tracks.
Don't delay - call the DNR & ask them for the biologist in your district! Give them the info ASAP cause rain can wash the tracks.
