On January 22, 2026, after the lunch break, Class 6b went to their science (NaWi) lesson. After a short video and an introduction by Ms. Colopy about the behavior of cats, all students received an information sheet that they were to fill out during the lesson—the topic was the “domestic cat.”

 

Together, the class sat in the foyer of the science building under the staircase and listened attentively as Mattis talked about his tomcat Karl. At the same time, the children filled in their information sheets. Mattis reported that Karl is a cross between a Bengal cat and a domestic cat, that he is very affectionate, a bit greedy, and usually quite relaxed. He also has a rare genetic disease in which his teeth become soft and fall out. We felt very sorry about that. We also learned how to take care of a cat. For example, the litter box has to be cleaned twice a week. Otherwise, a cat basically takes care of itself. It was especially nice that Mattis allowed Karl to be gently passed around so that everyone could pet him.

 

After the presentation, the students were allowed to ask more questions, pet Karl once again, and calmly finish and hand in their information sheets.

 

At the end, Nina, Feli, Lilith, and I were even allowed to hold Karl in our arms. When the lesson was over, a few students stayed behind briefly to say goodbye to Mattis and Karl.

 

This is how a special educational science lesson ended, and everyone went home happy.
