In Holleschitz one waits in vain for the arrival of tomcat Mikesch. He has been missing for three weeks. Nobody knows that he has been hired by a circus in the meantime. But one day Mikesch telegraphed home, saying he was homesick and wanted to return soon. When the time finally came, Bobesch, Paschik, Maunzerle, his grandmother and even the cheeky Tonda gave him a warm welcome.

Rain, hail and storm make Kater Mikesch's way into the world difficult. Soaked, he is picked up by a travelling circus. Since he can speak, he seems suitable for the circus people to participate in the program, and because he must of course have an artist's name, he is called Don Miko de la Maukando from now on.

Kater Mikesch is on his way into the big, wide world, which for him is initially only twenty kilometres away from Holleschit. He has survived one adventure with robbers well, another with the gypsies proves to be much more dangerous. Mikesch is held captive. The retarded, Paschik, the piglet, and Bobesch, the goat, are very sad about Mikesch's cat excursions. But in the meantime they have found a new playmate in Maunzerle, a small kitten. They teach it to speak and are surprised when Maunzerle is allowed to go to school with a new suit.

The goat Bobesch, one of Mikesch's friends, has also learned to speak. This has created a very funny cloverleaf: Mikesch the cat, Paschik the pig and Bobesch the goat. On his way through the wide world, tomcat Mikesch meets two robbers who try to attack him. At the last moment, tomcat Mikesch can save his skin. He continues to try to earn money to replace his grandmother's broken cream pot.

The clever tomcat Mikesch can not only speak, he can also ride a motorcycle. He and Paschek, the piglet who has learned to talk about Mikesch the cat in the meantime, visit a fairground. They drive a merry-go-round, "hit the lucas" and have fun with lots of sweets and various drinks. Tomcat Mikesch seems to have a hangover the next morning, the most terrible accident of his life so far happens to him - he smashes the cream pot. Unhappy about this and afraid of his grandmother, he goes out into the world to earn money so that he can buy his grandmother a new cream pot.

Tomcat Mikesch, a clever and good animal, learned human language from a cobbler. Kater Mikesch behaves as some parents would like their children to. For many he could be a role model.
