What does a city cat do when it sees a live mouse for the first time?
This is one of the most important things in the world.
It depends on the cat.

My half-year-old Taichun, first in May of this year, when he got out in nature and saw a thick, splinter shovel in the garden, almost knocked his sister off his feet and got into the bed like a meteorite. The lion, right away, washed off, but this body after half an hour wrapped a half-meter hump.
Further, it had to be strictly controlled, because the neighboring chickens and rabbits handled the beast unusual - closed in the house, walked on a guide (trained for a week).

But Kun, three years older than him, when he saw a mouse on the floor, first looked at it.
His eyes were square, full of horror, and he refused to get out of the closet. I had to put the pillow on the closet, and walked only on the pen. 10 kg in cattle, however.
