Natasha is a lonely, middle-aged admin employee at the zoo who still lives at home with her mother. One day her life is turned upside down when she discovers she has grown a tail… A realistically structured story into which the director deftly inserts a fantastic motif in a film that speaks of loneliness, otherness, fear, and also of the courage to be different. 《动物学》的别名有：Zoology。
