According to Sergey Lukyanenko:
I have long understood that cats are people a little more crazy than even dogs. Probably somewhere at the aquarium level.
I eat breakfast and watch TV. There shows some institution of "cat therapy", where people with a shady glow in their eyes claim that cats relieve from all illnesses and diseases. And I hear something from which I drink hot tea.
One old woman had high blood pressure, and she was almost dying from a hypertensive crisis! She was lying on a layer, like dead... But fortunately, her cat came to the rescue – procured the old woman’s vein and thus lowered the pressure!
As for me - so simply the cat was impatient, decided that the old lady has already given an oak and you can start...
