The goal of National Cat Day is to increase awareness of the millions of cats who need good homes. If you have room in your house to provide a loving home for a cat, please adopt a cat today! National Cat Day was founded in 2005 by Pet Lifestyle Expert & Animal Welfare Advocate, Colleen Paige, to encourage cat lovers to celebrate the cat(s) in their life for the unconditional love and companionship they bestow upon us.
