Here is a more detailed description:
Tigers may not be the king of the jungle, but these striped cats are no softies! Magnetic and self-possessed, Tigers are born leaders. They have an air of authority that prompts others to fall in line, which is exactly how they like it. Although they are magnetically charming and fun to be around, Tigers like to go it alone sometimes too. A Tiger's main interest is in following its ambitions -- and maintaining control.From this astrology site.
Tigers are courageous beyond compare and generally come out ahead in battle, be it in the boardroom or the bedroom. Seduction is one area where the Tiger is definitely king! Noble and warm-hearted, Tigers have a natural, raw appeal that's extremely attractive to other Signs. They're not just about attraction, though; ever on the side of right, Tigers will fight the good fight to the bitter end if the cause is worthy. Opponents are wise to fear this feline.
A bit of caution is a good thing around Tigers, since they can pounce without warning. They experience mood swings and often feel things more intensely than others, the latter quality being both good and bad. They can react poorly under stress and are prone to emotional outbursts. This Sign's bristling sensitivity can send friend and foe running for cover.
A lesson that Tigers would be well-served to learn is "moderation in all things." Once these cats can find their center and direct their considerable energies toward worthwhile endeavors (as opposed to racing through life), they will accomplish much.
Tigers are most compatible with dogs and horses and least compatible with oxen and sheep. A tiger/tiger pairing is difficult and generally not recommended.
Famous tigers include Stevie Wonder, Leonardo DiCaprio, Steve Irwin (the crocodile guy), Stephen Chow (the Kung Fu Hustle guy), Marilyn Monroe, Karl Marx, Oscar Wilde, Mel Brooks and crazy Tom Cruise.
