The small kitties were silvery while being crowded in a farm building and cautiously changed the color
Once a man while opening the door of the farm notices small kitties. Each of them had individual colors. He took the pets to a refuge where the volunteers saw natural coloring. They supposed that it happened when cat was in depression or was ill while being pregnant.
At first sight their color seemed to be gray. The volunteers were able to catch their mummy while seemed not to be quiet. Firstly it was hard for the cat to be accustomed to a new environment.
Day by day the cats were more cheerful and energetic. And their color changed from grey to black.
