ミルキーパニック twelve

The town of Milky Town has a problem. All of the animals are drinking the milk from the company Milking, and are slowly turning into cats who have lost all motivation. The cat Milking hatched the evil plan in order to take over the world. By chance, Ippon, a tiger cowboy who used to work on the Charmy ranch, returns from his wanderings to Milky Town. There, he realizes the truth of what's happened to Milky Town, and works to save it alongside his friends. (Source:Anime News Network)
