The totally made-up holiday honors the felines we love to pet.
In honor of the day, here are 5 facts about our cats.
Sweeties
Cats do not have sweet tooths. Unlike other mammals, they lack the ability to taste sweetness, according to Scientific American.
A little nip
Researchers believe cats like catnip because it "mimics feline 'happy' pheromones and stimulates the receptors in the brain that respond to those pheromones," according to the Humane Society.
Boxed
Many cats like boxes because they "resonate with their instinct to find protected spaces out in the wild where they are able to see their environment without being seen," according to Purina One.
Lincoln love
Abraham Lincoln loved cats. When Mary Todd Lincoln was asked if her husband had a hobby, she replied "cats," according to the National Park Service.
Nap time all the time
Cats love their beauty rest. It is normal for these night hunters to sleep 16 to 20 hours a day, according to a Chicago Tribune column.
