While a bit on the simple side, Oruorane the Cat Player works as a light slice-of-life drama focused on a young man developing a bond with an old man who trained his cats to sing following his loss of an orchestra job. The OVA appears to want to express the hardships that come with adult life, shown with the cold, wintry city setting and the struggles faced by those attempting to get by with their lives, particularly the young man's situation. However said challenges don't necessarily mean it's wrong to seek a temporary escape from it as the young man is granted the opportunity tolearn how to use the old man's cats to learn how to harness their abilities for himself. The simple storytelling fits reasonably within the OVA's 30-minute runtime and will admit the antics of the cats had their amusing moments for me. Only major shortcoming I'd say this could have is its rather simplistic visuals, though I'd say the art style does work to fit the anime's intended tone. While I'm not sure if I may think much of Oruorane down the line given the OVA's obscurity, I don't regret the time I put into watching it given the simple slice-of-life story it tells about a down-on-his luck young man getting a temporary escape from his problems and I'd at least recommend watching it once.
