DOG "ZABLA" A HALF YEAR AFTER LABYRINTH DESTRUCTION

The animal, with eyes open, was taken (solid line) to a new place of feeding, So, at the sofa, behind a screen. Released 1 minute later, she went spontaneously (broken line) to foodbox 1, then to the left corner where she had been fed some time ago and only then to the present food location. The dog went first to all the places where she had been fed previously.
