A woman in Norway has taken the idea of being born into the wrong body to an entirely new level.

20-year-old Nano says she's actually a cat on the inside and believes she has super-sharp hearing and night vision which allow her to hunt for mice.

Nano says she realised she was a cat when she was 16, and has been adopting feline mannerisms ever since.

Now she has implanted whiskers...and wears a tail.
