If you're looking for anime similar to Neko no Robu, you might like these titles.
On a distant southern island, a fish (sakana) opened its mouth for a cat (neko), thus "nekozakana" (cat-fish) is born.
Zero and Shito are two cats who live in a typical neighborhood, underneath a household kotatsu. Together, the two interact with their friends such as the pink dog Hana and have other fun adventures along the way.
The cute and mysterious cat-like creatures called Mitchiri Neko that seem to gather around each other if you leave them alone now get their own anime with a glorious voice cast! The free and happy-go-lucky Mitchiri Neko’s daily life is filled fluff and surreal laughs! Say it with me, “Mitchiri! Mitchiri!”
