Lilli is a seven week old calf and she's got six legs. Mutation is gross, but at least Lilli lives. She beat her veterinary's prediction that she wouldn't last after birth either but she's now living happily in Switzerland.

Her six legs—two of which grow on her back are pretty hideous looking no matter how you want to see it.

But she's not the first. This cow is just one of the many cows that have been born with this mutation through history. [Mirror]
