Wagahai wa Neko Madoushi de Aru: Kijitora Luke no Kaiteki Cheat Neko Seikatsu

After saving a cat from being hit by a car, a young man named Negoro Kaito is reincarnated into a fantasy alternate world. However, he is now a tabby cat! This is the story of how he becomes a super-powered cat and is picked up by a young noble girl, popularizes tomatoes, and occasionally saves various people, all while striving for a life with three meals a day and a nap (he provides his own snacks)!
