Another interesting factoid about black cats. (They are healthy.)

THE GENE THAT CAUSES BLACK FUR MIGHT MAKE THESE FELINES RESISTANT TO DISEASE.
The mutation that causes a cat’s fur to be black is in the same genetic family as genes known to give humans resistance to diseases like HIV. So perhaps their color has less to do with camouflage than disease resistance. Scientists hope that as more cat genomes are mapped, we may get a step closer to curing HIV.

Hummmmm. Any black cat owner could tell those scientists that black cats are — well — special.
