Cat purr
 
Cats can purr, indicating that the animal typically is under a state of placidness. However, purr may also mean that is distressed, afflicted or experiencing pain. Cats purr in the presence of other cats, for example, when a mother is with their pups. There are many theories that explains how they purr, including: vibration of the false vocal cords when inhale and exhale, the sound of the blood flowing through the aorta artery, vibration of hyoid bone or direct resonance in the lungs. However, now believe that the purr is the result of rhythm impulses towards their larynx.

Cats can purr and miaow simultaneously, especially those who vocalize heavily. In addition to purr, in a state of relaxation can flashing slowly or partially close their eyes, indicating peace and serenity in a determined situation.

In any case, the purr can be a way to calm down itself, for example, when they are sore. Although is not proved, studies suggest that the frequency in the vibration produced by the purr can promote the healing of the bones and of the bodies of the animal, explaining why purr when they are injured.
