April 11th, pet day

National Pet Day was founded in 2005 by Pet & Family Lifestyle Expert & Colleen Paige, who also founded National Dog Day, National Puppy Day and National Cat Day {among others} to celebrate the joy pets bring to our lives and to create public awareness about the plight of many different kinds of animals awaiting a forever home in shelters all across the nation. Almost any non-exotic animal you can think of, from dogs and cats, to small animals, farm, reptile and avian...there are pets who need your love.
