National Cat Day is celebrated annually on 29 October in the United States. It was founded by animal welfare advocates Colleen Paige and Adam Olis. The National Cat Day website states that the holiday was first celebrated in 2005, “to help galvanize the public to recognize the number of cats that need to be rescued each year and also to encourage cat lovers to celebrate the cat(s) in their life for the unconditional love and companionship they bestow upon us.” The day is supported by the American Society for the Prevention of Cruelty to Animals, a nonprofit organization which also works to encourage pet adoption. An International Cat Day, was also created in 2002 by the International Fund for Animal Welfare and this takes place annually on August 8th. World Cat Day is also celebrated on 17 February, in much of Europe and on 1 March, in Russia.
