Let’s celebrate National Cat Day by reveling in one of the all-time favorite feline activities: sleeping.
Cats are expert sleepers. They certainly take a lot of time to practice. The average domestic cat spends around 16 hours each day sleeping. Wild cats sleep even more, between 16 to 20 hours a day. BuzzFeed assembled an awesome collection of photos of cats sleeping in an impressive array of awkward positions. These are our favourites.

Head over to BuzzFeed for individual photo source credits and to see the rest of the collection of snoozing kitties.
