Bibi Blocksberg

Bibi gets a little black cat from her grandmother. The initially skeptical parents are surprised: Silvester is well educated. He even teaches Bibi to tidy up her room and helps mother Barbara in the household. Unfortunately, the cleanliness of the cat takes on such proportions that even the house starts to bubble because of all the cleaning agents. Desperately, Bibi and her mother try to get rid of the cat.
