Shifters Unbound - Series by Jennifer Ashley

Twenty years ago, shapeshifters were involuntarily outed to the world. Faced with extinction, many of them banded together and allowed themselves to be shunted into Shiftertowns - ghetto areas that no humans wanted. 

Now they are second-class citizens, forbidden from higher learning and holding high-paying jobs, prevented from using higher technology, and forced to wear Collars to control their hunting and fighting instincts.
