the vets have researched it and found no side effects
in that film, the big tomcat (what clearly looked like a alpha male) was getting so trashed he was drooling, even those kittens seemed to have eventually stopped fighting over the catnip and were rolling about
and the sort of modern Germans what make nature docs are usually really full on about animal rights so if they thought it was bad some yoghurt weaver type dude with a beard probably would have shouted “Achtung Katzen! Raus! Raus! Raus! Keine Katzenminzen für Sie! Es ist gefarlich für die Gesundheit!”
Those cats are doing a better job of self-regulating their drug use than humans. TBH I think they are the only species in the EU allowed to consume plant-based recreational drugs in this manner!
