Cats regularly clean themselves throughout the day. Right now, we are in the middle of a drought (die Dürre), and need to preserve water. Hence, live more like a cat.

Katzenwäsche
Besides the daily shower, I had taken extra ones throughout the day, but the City of Oberursel sent out a notification to ask us to preserve water for the coming days/weeks.
This means, I still get to take my daily shower, but during the other times of the day, I have to contend with a Katzenwäsche.
Definition: kurzes, oberflächliches Waschen (a short and perfunctory washing of the body)
Beispiel: Ich bin spät dran für die Arbeit. Ich habe keine Zeit für eine Dusche. Ich mache eine schnelle Katzenwäsche.
