Meet Matilda, the 'alien cat'

This 2-year-old cat named Matilda, suffers from spontaneous lens luxation which causes her eyes to take on an alien-like quality. Matilda's owners said her eyes were perfectly normal until around her first birthday, when  one pupil became enlarged and stayed that way for several minutes before going back to normal. Several days later, the same thing occurred.
The cat has since become an internet sensation.
