The Inspiration for the Cat Door

From the Heart

"Necessity is the Mother of Invention"
There is nothing complicated about a cat door.
It was a cat who constantly interrupted his work
that Newton designed the door for.

Newton was one of history's greatest
mathematicians and theorists,
whose work demanded full concentration-
But his pets, who competed for attention
were a constant source of aggravation.

Historical Footnote:
During his lifetime, Newton made numerous contributions
to science, including developing the laws of celestial
mechanics, codeveloping calculus, and conducting
groundbreaking work on everything from the nature of
light spectra to measurements of the speed of sound.
But few realize that Newton was also a pet lover, or that
sometimes his numerous animal friends could drive him
to distraction.  For instance, he once suffered an emotional
breakdown when a favorite dog knocked over a candle
on his desk, burning some of his important research notes.
Frustrated, the scientist designed and implemented a
solution-- the pet door.
Today, every feline blessed with the ability to enter and leave
a room without troubling his or her human friends has
Newton (and his restless charge) to thank.
