cats purr for different reasons.
cats purr as a way to show they are content and happy
some cats also purr when they are sick, frightened or even close to their death.
There are many theories to explain how the purr is generated. One study determined that purring involves activation of nerves within the voice box. These nerve signals cause vibration of the vocal cords while the diaphragm serves as a piston pump, pushing air in and out of the vibrating cords, thus creating a musical hum. Veterinarian Neils C. Pederson, author of Feline Husbandry, believes that purring is initiated from within the central nervous system and is a voluntary act. In other words, cats purr only when they want to.(http://www.petplace.com/cats/why-do-cats-purr/page1.aspx)

Good point kaiote, I have been involved in animal rescue for many years and a dog wagging its tail is no sign that it wants to get to know you, it just means it is alert enough to know there is some action going on, and that can be misleaingly dangerous.
