This is good comic and a rather different way of seeing the evils of the Nazi regime. As a cat lover, I object to the cats being cast in the role of the bad guys, but I get it - cats hunting mice etc. I had this book as a present because it was thought to be a good idea for a person learning German.
However, beware; the German here follows Jewish speech paterns, eg Ich habe gefunden einen Spezialisten. instead of Ich habe einen Spezialisten
gefunden. However the comic is very interesting.
