Scientists can't explain Venus the cat's odd facial coloring
Venus, a three-year-old tortoiseshell, entranced the internet last month with her striking colors, but scientists can't seem to explain her unique face. One theory is she's a chimera (a cat with two types of DNA from fused embryos). However, because she's a female, she has an extra X chromosome anyway so there's no way to tell without an expensive DNA fingerprint. Plus, it still wouldn't explain the baffling blue eye. Another theory? "Absolute luck," says UC Davis professor Leslie Lyons.
