The cats tried to destroy all the dogs, however, they destroyed all the dinosaurs instead. The dogs then created the human bible and said the "God" created earth. So that's why "God" is dog spelled backwards. When that didn't work The Kitty Council decided that they would go to war with the dogs. Years later the dog councilor and Mittens signed the Great Neutrality Bill of Cats and Dogs. And thats the Religion of The Kitty Kingdom. Thank you.
This was a reply to an ass hole forcing his religion onto others, made my day.
