"Mitchiri Neko" is a short-form anime series that revolves around a group of mischievous, anthropomorphic cats who engage in playful and often absurd antics. The narrative is episodic, with each episode featuring the cats in various humorous and surreal scenarios. The cats, each with distinct personalities and quirks, interact with one another and their environment in ways that defy logic and reality, creating a whimsical and lighthearted atmosphere.

The main characters include a white cat with a laid-back demeanor, a black cat who often takes on a leadership role, a pink cat with a cheerful and energetic personality, and a blue cat who is more reserved and thoughtful. These characters, along with a rotating cast of other feline friends, navigate situations that range from everyday activities like cooking and playing games to more fantastical events such as space travel and encounters with supernatural beings.

The plot lacks a continuous storyline, instead focusing on self-contained episodes that highlight the cats' interactions and the comedic outcomes of their actions. The humor is derived from the cats' exaggerated expressions, slapstick comedy, and the unexpected twists that occur in each scenario. Despite the lack of a overarching narrative, the series maintains a consistent tone of playful absurdity, appealing to viewers who enjoy quick, light-hearted entertainment.

The series is characterized by its minimalist animation style, which complements the simplicity of the stories and the exaggerated nature of the characters' actions. The brevity of each episode, typically lasting only a few minutes, makes it easily digestible and suitable for casual viewing. "Mitchiri Neko" does not aim for deep storytelling or complex character development but instead focuses on delivering quick bursts of humor and charm through its quirky feline protagonists and their unpredictable adventures.
