52 puppies were used to portray Napoleon over the course of the 28-week shoot, with anywhere from three to eight being used for a single scene. This was because the puppies slept a lot, cutting down filming time, and because a puppy could only be used for three weeks before it grew too big.
MOUSE... MUST... DIE.
Napoleon: H-huh... good thing I'm not a mouse...
Cat: Ahh, but you are a mouse. A big, yellow mouse.
When Napoleon meets the "owl", it is not actually an owl. The animal is actually a Tawny Frogmouth.
Two English versions exist: the original Australian cast and a dub with an American cast.
