70's or 80's post apocalyptic cartoon with animals.
Hey there to anyone who can help. I have been searching all over for this cartoon I remember a bit as a kid. The beginning of the movie has a voice over of one of the animals, an owl I believe. He is telling the story of how all the men in the world went to war and fought until there were no more men. The solders were all wearing gas masks and the only visual I remember from the film was the last two men intrenched. One shoots the other, then the other one gets one last shot off before they both die.
I really hope someone can help me with this. It has been bugging me for years.
Thanks!
