Cats are known to have a strange habit of staring unblinkingly into space.
From the outside it looks creepy, but in fact there is nothing unusual in this look of the cat.
If a cat is staring into space, it most likely means that it is watching some small insect or particles in the air that the human eye is unable to see.
Cats' vision, by the way, is seven times sharper than humans'.
Cats also have a frozen look when they listen or smell something.
Additionally, staring into space may indicate that the cat is in a state of deep relaxation.
