Funny, but that site proves absolutely nothing.

#1 it comes from a site that purposely believes cougars exsist here in natural state with a breeding population (ie not just releases).

#2 I see no evidence whatsoever in that page that shows scientific results. All it does is talk, talk, talk talk, with no proof. Show the analysis sheets by the agencies, etc. for real proof. Or even compliment that with a quote from one of the staff members who worked on the cases.

#3 I liken this site to sites that try to persuade others about alien invasions, etc. Tons of evidence that is purposely left out, or tweaked to make it believeable without direct proof. Like calling the sightings CONFIRMATIONS.... If it were a confirmed event, the site would have much better evidence that proved their case, and yet again, I see none of that.

I agree that releases from pet/animal owners may have happened, but having a natural living wild poulation is absurd without better indicating proof.
