Cats do not blink like that.
Not convinced...
Why do cats' eyes contract to a vertical slit?:
Cats evolved to be nocturnal hunters, and they can see well in very dim light. Because their eyes are so sensitive to light, cats need precise control over the amount of light reaching their eyes.
Being able to reduce the pupils to slits rather than tiny circles gives the cat greater and more accurate control of how much light enters their eyes; this ability is particularly important in bright sunlight.
Human beings have round pupils; cats have pupils shaped like vertical slits. What’s the advantage for cats and people, respectively, in those different pupil shapes?
Different pupil shapes seem to be an adaptation to different activity patterns during a 24-hour day.
Nocturnal Animals And Slit Pupils
Cats belong to the category of nocturnal animals, who do most of their foraging for food at night. Other nocturnal animals include rats, bats, mice, flying squirrels, and owls.
These animals rely heavily on hearing and touch to get around, but they also have the ability to see in very dim light. Their eyes have big lenses and sensitive retinas.
That's no cat!

So they got to you too, eh?
That is why the method is used. It works and the results are unbelievable.
