Gary Larson had a short-lived animated show. Larson is famous for the juxtaposition of ideas to make people laugh at the way things are. In this case the army of cats and dogs fought each other. Note that the cats have a flag somewhat similar to the Union, while the dogs have Confederate kind of flag, but instead of stars on bars, it is crossed bones.
The finial of the cat flag is paw with nails extended, while the finial of the dog flag is tail.
