They also eat mice. When cougars get angry they hiss and growl. They communicate by yowling. Cougars receive sound through their ears. The sound travels through air.
Cougars have four different names.
Panther, Mountain Lion, and Cougar. The female hums for communication with their wings. They also can receive sounds with their antennas. The sound travels through the air, but what is really cool is that they suck your blood. Even though it hurts me it is cool.
