National Cat Day is celebrated Oct. 29 every year in the United States. It was founded in 2005 to celebrate the love for cats, the world's favorite pet, and to raise awareness about the number of cats that need to be rescued each year.

Animal welfare advocate Colleen Paige, along with Pet Lifestyle Expert, recognized the day aiming to find homes for 4 million cats that enter shelters every year and draw attention towards the 1 million to 2 million that are euthanized annually. Paige said the goal of National Cat Day is to arrange the adoption of 10,000 shelter cats nationwide every Oct. 29.

"Often cats are overlooked and under-appreciated because they don't usually have jobs like dogs. But cats still lower blood pressure, offer unconditional love and companionship, tons of laughs and alert their owner to danger. Many cats have been named heroes," according to the official website.
