For myself, I've found the GURPS system very friendly for furry players. Their core book and the compendiums that go with it allow GM's to design just about any furry race their hearts could desire. Even if you are just running a fantasy-based game, their Fantasy Races book contains reptile men, intelligent horses, centaurs, winged folk and Great Eagles akin to Tolkien's. The system may take a bit of work but it's the most customizable that I've run across
