People often report cougar sightings far outside of the scientifically accepted range for the animal, leading to many "phantom cat" type reports. More and more however, it seems science may have to reconsider it's view.
National Geographic has put up a map that shows confirmed cougar sightings outside of their normal range. These sightings are only those confirmed by state wildlife officials in each state. If we were to add unconfirmed reports, we would no doubt see much more evidence of the cougar’s migration to the east.
