“Butyric Acid is a effective liquid to stop people from paying to see animals in prisons, when poured over entrance and cash desk. Stop to finance such violance in zoos! Animals are not here to gape at!
So we reached out to remember them to respect all beeings. Close the Zoo Wilhelma, and all other animal prisons!
Until every cage is empty!”
