Sorry to hear this.
Reminds me of the mountain lions that are routinely killed on So Cal’s freeways, very sad since there are so few of them left.
A new “animal bridge” is being built over the 101 freeway to try to prevent this and also to help with inbreeding issues since the freeway bottled up the lion population on either side.
There are more than enough. Many of them hang around suburbs and eat pet cats and dogs. More than a few humans have been attacked, a few even killed and eaten.
Distribution: Other than humans, cougars are the most widely distributed land mammal in the Western Hemisphere. Cougars range from northwestern Canada to Patagonia, South America.

There are fewer where you live because they won’t stay off the roads.
There are plenty everywhere else.
