NY an Pa DEC/DNR have only recently(past 6 monthes or so) changed their tones towards these reported cougar sightings in our area.
They have gotten enough from credible people where they are actually starting to investigate the possibility of cougars in our area a bit more.
If you happen to see a cougar in NY or PA I urge you to stay aware, mark the locations, take time to look, watch, listen and then physically try to find any tracks. If you feel daring ..... follow it. Use caution.
Cast the tracks or picture them with something in photo for size.
The states are now asking for reports
For NY
