You guessed right; this is a very sweet cat friend of mine :) i also drew a car because i last saw her like this that evening: she followed me until the gate and stopped there, as if she was afraid to go beyond that border. and she looked at me just like that in a kind of sad way from behind a parked car.
now i see her everday, sometimes give her some food and play :)
thank you all and special thanks to ausiuke for the best wishes. i wish the best for all of you too.
