1. Because it’s warm
Cats get cold easily,
so they always rest in warm places.
If they come up on you while you sleep,
it is likely that your face feels warm to them.
When people sleep,
they exhale warm breath through their nose and mouth;
when this happens, the body heat escapes through their head
and that’s why cats feel that their owner’s face is warm.
2. Because they want to act like a baby
Cats deliberately sit on their owner’s face
to attract attention
when he does not look at them.
This may be a bit too much for the owner,
but such behavior does not mean
that they want to harass the owner.
Rather, it may be because
they think of their owner as the mother cat
and thus they’re acting like a baby.
Therefore, if your cat comes up on your face while you’re sleeping,
it could mean that she is feeling lonely
and hence you should increase the amount of time you spend expressing your affection
during your waking hours.
3. Because they trust you
If your cat sits on your face,
you can consider it a huge expression of her trust.
Most cats are sensitive and easily frightened,
so they do not approach people they don’t trust.
For cats, the “mouth” is a body part
which can be attacked at any time,
so it means that they highly trust the owner
if they approach the mouth area first.
Furthermore, if they place their belly, which is a weakness for them, on top of the owner’s mouth,
it means that they have great faith towards the owner.
4. Because they like your scent
Cats who highly trust their owner
feel secure through the smell of the owner,
so they like to rest in the owner’s room or on his pillow.
Also, in general, cats have a habit of sleeping
only in places that they consider the safest.
Therefore, if cats come near their owner’s head,
it is likely that they feel safe by his side.
This is because the area near the owner’s head
is one of the areas where they can best smell the owner’s scent,
and thus gives the cats a greater sense of security.
