There are many GURPS genre books which can help with building nonhuman characters - Space, Fantasy, there's even a recent Furries book for anthropomorphic nonhumans, the old 3e Monsters/Shifters books are, well, less helpful but neat.
The Technomancer setting (really neat modern day magic setting, albeit one that drops the line "a resurrected Stalin fights to take back control of the USSR" and barely follows up on it - the Penguin Hivemind gets more attention) has a half dozen human-animal chimaera races that were updated in a later issue of Pyramid.
