Language includes use of 'fricking', 'God' and 'screw up'.
There are regular scenes of comic violence, in which cartoon animals fight with a variety of weapons, including baseball bats, clothes irons, axes and chainsaws. Injuries are bloodless, comically stylised and fantastically transient.
There is rude humour: a dog fouls a pedestrian crossing, and causes humans to gag with its flatulence; a mouse makes photocopies of its bottom. There are very mild scary scenes when then cat and mouse are taken to an animal pound, where other animals menace them. There is a reference to animals mating. The cartoon characters drink alcohol.
