The military should model their stealth vehicles on panthers. If they can be so common but remain undocumented for so long, they have incredible powers.
Actually, maybe the politicians and criminals could get some tips from panthers too! Seen by countless witnesses, but without a shred of evidence! Incredible! They manage to disguise their footprints as those of other species, and they are masters of disguise, appearing like more common animals when captured on film. They even fool DNA tests from time to time! Not a single speck of evidence! Awesome creatures.
