Originally, I was not going watch Mayoi Neko Overrun! because it did not catch my eye. Since I been watch mediocre anime lately, may as well go all out. At first, this looks like you typical harem anime targeted towards the otaku crowd. And it is, but this its pretty funny.
To sum up what happens, a cake is eaten by a little boy and he blames it on a big cat he saw. Takumi and friends make a new cake but they need egg. As they return home, they see this big cat like creature and they chase after it. They end up losing track of it and the little boy tells the truth.
