An incredibly disturbing dance sequence takes place in which contorted and disfigured rats have violent spasms while jolly music plays. Young children may be incredibly disturbed during this scene. The rats also make horrifying moaning and distressed sounds.
The cat's animation is disturbing.
Some may be disturbed by the glitch-ridden, half-hearted animation. Some models look unnatural; a cat in one scene chases a mouse around a human kitchen on its two hind legs, grabbing at it with clawed gorilla hands (that were intended to be paws), for example. Nothing disturbing beyond this, however.
