Kat-Zen?

...rather Katzen, pl. of German Katze (= cat). Ruminations while spending 1.5 hours of the night with Malu at Egelsbach veterinary hospital because of her high breathing frequency. (From our waiting position I could not see the dogs’ inscription.) The same place where Cooper had been terminally diagnosed with cancer, it was quite busy at night too, but the staff was most friendly and highly supportive. It turned out Malu is suffering from acute bronchitis and receives an antibiotic and an anti-inflammatory drug. Back home by 3.30 am, the night became short.
