Cat Shit One was a Japanese manga set in the Vietnam war where the humans were replaced with animals. A short film was made with the aim of getting enough funds to turn the book into a series, however they only managed to get as far as the initial episode.
This is a shame as it's great! Moving the action to Afghanistan you have 2 rabbits decked with weapons straight from Metal Gear Solid taking out camel terrorists. It's bonkers but it kind of works and I like it's treating itself very seriously with no reference to them being rabbits at all.
