Yes they do. http://en.wikipedia.org/wiki/Tiger#Man-eating_tigers
We're not prefered prey but they'll settle for us once in a while.

Unless of course you want to sell your house and give the money to the WWF so they can create a wildlife reserve. Please don't dictate how other people should interact with their environment from the comfort of a 1st World setting.
