I've noticed this with my cats over the years and with the cats of friends and family. Quite often, though not always, the cat will tuck their head down and under, perhaps into a pillow, a gap in a couch, or even into the crook of your arm. The question is... why? It seems counter-intuitive to self-defense to do that.

  • The only part of the cat's body that has no fur is the nose and the bottom of the paws. Note that all of these are protected in the tucked in position

  • If you could ask the cats why they do it, they'd just tell you it's comfortable. Most mammals adopt that kind of pose when sleeping, so this is probably something that cats get as part of the standard package of behaviors that come with being a mammal. We don't do it because our spines don't flex enough in the right directions to let us do so... but even so it isn't unusual for humans to curl up in "fetal position", especially when cold

It is not so counter intuitive for a cat to sleep curled up as you suggest. Protecting the head whilst sleeping is not counter-intuitive for safety. If you think about it, it is, perhaps, the safest position to sleep in. The back is exposed and all the soft belly and face is protected. Even the hard skull at the back of the head is a like a little armour.

Sid Curled up

As opposed to a stretched position, where this picture illustrates well the soft underbelly that the cat is protecting.

Sid stretched

Dogs will often sleep rolled up in a ball also, it's good to observe when they do and when they are relaxed enough to lay out stretched, or even have a play stretch.

It's also noteworthy that animals will find the safest place to sleep.

    Many of them will find themselves hidden spots to sleep, too, or places where they're camouflaged (we might not think so - they don't see colors the same way we do).

    Mine sleeps between a chair and a wall, which conveniently is also right in front of a heater vent (I live in Minnesota, so we need heaters on in the winter, in case you live in warmer climates)

  • Mine will paw open low cupboard doors and crawl up into the drawers to take a snooze :p

An additional thing to consider: Cats like warmth. Curling up vs stretching is the ideal sleeping position to maintain body temperature, or keep warm when the temperature is cold for all animals, as well as humans. Taking that into account, tucking one's head is an additional way to keep warm.
