A few mild verbal references.

A chimpanzee bounds over to a window and smashes it. A man is seen slapping and messing about with a bobcat (the bobcat looks quite agitated during this). A large cat is shot with a tranquilizer dart. Several references to animal attacks, including references to an infamous incident where a woman's face was ripped off by a chimpanzee.

A couple of F-words and some uses of milder swear words.

A man is briefly seen smoking a cigarette.

There are some moments in the documentary that show very restless animals locked up in cages. These moments might upset some people. A man casually walks out with a large white tiger on a chain, much to Louis' horror. A few of the attitudes expressed throughout the documentary might slightly offend some people.
