horse + donkey = mule
zebra + donkey = zonkey
cat + rabbit = cabbit
those are only the one's that I've heard of. The offspring are almost always sterile, I've only heard that once has two mules mated. If the species are closely related enough, like in the genus or something(I don't remember biology that much), however I'm pretty sure there isn't anything close enough with humans to mate with them.
