Sleepy Kitten's Adorable Open-Mouth Nap Will Have You Saying Awww

A tiny, fluffy kitten taking an open-mouth nap might be one of the most adorable things ever. That hardly seems fair, given what humans look like when they do the snooze on a bus or a plane. But after watching the August 2026 TikTok video below, you can't argue with nature: A kitten peacefully catching flies with their yapper will always be a trillion times cuter than when their owners do it.

The hilarious video uses a popular TikTok sound that says, "You will never be as tired as a cat who's done absolutely nothing." The video's funny caption echoes similar sentiments: "Bro is so tired he forgot to close his mouth." Still, just above the kitten's head is another feline taking a catnap, only with its mouth closed, so it likely has more to do with their different sleeping positions and not their level of tiredness.

Judging from all of the sleepy kittens posted in the comments in this video, as well as the many others using the TikTok sound, there are more relaxed, happy cats where this came from. Even the same creator reused the audio on another adorable TikTok video featuring his other floof.

Kittens sleep up to 20 hours a day, partly because they're still growing and developing. Adult cats sleep a lot, too, resting up to 16 hours a day — because hunting and playing are really exhausting. Between that and their love of eating, you'd think cats were going through a constant growth spurt. 

In addition to hunting and playing, cats have very different sleep schedules than people do. Cats are crepuscular animals, which means they aren't exactly nocturnal but are more active at dusk and dawn. Cats also take frequent 15- to 30-minute naps throughout the day, so it may look like they're almost always sleeping because that is what their owners see. And compared to how much sleep humans need, the contrast isn't as cute as the kitties in the video. 

Whether they're sleepy kittens or drowsy cats, it's reasonable to worry about your pet at any age. However, veterinary experts recommend focusing on how they behave when they're awake, not how many hours they sleep. You might be jealous of the hours they sleep, but know that if they didn't sleep so much, they would have more time to knock things off your counters. Unless they're not eating or seem lethargic when they're awake, let sleeping kitties lie. Now, check out these 16 adorable kittens who are still learning how to cat.
