This is my entry! It is ten seconds, if you count the intro part. I used the scratch wait thingy to time it so it should be accurate. Basically, it is a scene in warrior cats where the cat in running to a battle to help their clanmates (A battle for extra territory, even though there is already enough food), and then an enemy unsheathes their claws to fight. Then, a cat claws another cat's tail. The first cat then gets angry (not specifically about a cat's tail getting hurt, that is meant to symbolize that the first cat's clanmates are getting hurt without getting too gory) and then the first cat tries to protect their clanmates and is about to hurt the enemy cats. Then, stopping the first cat, it starts raining. The cats realize how silly this battle is, and head back to camp, sad that they hurt cats over a patch of grass that they don't need for food. Honestly making the rain a separate sprite would have made this soooooo much easier but what is done is done.
