The iPhone 5S was released to a lot of fanfare.  One of the new features is the fingerprint scanner to unlock the phone instead of entering some sort of code.

By all accounts, the fingerprint scanner works well.  But this is interesting ... it also works using the "fingerprints" of a cat! According to

The cat’s paw worked, and while it encountered more frequent failures than did a fingerprint, it was able to unlock the phone again repeatedly when positioned correctly on the sensor. Note that no other paw pads would unlock the device, and that cats essentially have unique “fingerprints” just like people, so this doesn’t make the Touch ID sensor any less secure.
