Why orange? "Orange is bright and reflective making it easier to find those furry little samurais when they run away."
But more importantly, "It brands your indoor cat as a convict."
Inman said the idea is to turn lost cats into found cats. That "we have fewer kitty funerals and more kitty birthdays."
"By putting orange collars on your kitties, it signals to the people of the world that your cat belongs inside. People of the world: if you see a cat running around wearing orange, know that they are an escaped convict."
Inman frequently does comics about cats, including the incredibly moving "When your house is burning down, you should brush your teeth."
The Facebook post for Orange is the new cat has reached over 10 million people.
