Exactly.
Cougars, Catamounts, Pumas, none are black.
Jaguars can be.
Don’t really want either one around. If you think your cats a jerk, well, these guys are bigger ones. They don’t just lick your face, they bite it off.
You are right; The existence of a melanistic cougar has never been confirmed.
Jaguars can be.
The only verified jaguar currently living in the United States is El Jefe, seen in the Santa Rita Mountains in Southern Arizona.
Don’t really want either one around.
ESPECIALLY not a jaguar.
