I killed 4 in this area, one by using bait, the three others when I was just rinding my horse back and forth and forced them to spawn and forced them to attack me while I was on my horse.
One spawned in this area when I was riding around and killed dear for food, it was the second time I have been attacked by a cougar along this river, so it’s worth a shot to try there as well:
Start riding above the picture of the fox and all the way down to the end of river text, turn around and ride back up, rinse and repeat .
It took me two real life days to kill all 5 cougars, almost a week in-game, so bring warm clothing with you just in case, I used the Grizzlies Outlaw outfit since it is suitable for average temperatures.
You will find elk in the same area as the cougars.
That wild Arabian horse is up north, bring the winter gunslinger oufit with you, because it’s cold and snowy up there, you will find it here somewhere:
I like my silver gray Nokota and I will stick with her .
