i used to have this cougar experts e-mail.we used to talk aout 1 time a month.he said that blood sample on wild cougar in chicago really opened up a lot of eyes on distance that male went.
he said hunting is reducing a lot of this to certain point.for a few years some areas banned hunting and cougars were getting more abundant.
which caused more cougars to expand ,i guess cougars dont like to be too close to each other.
