The animal theme was well done, and I enjoyed the character design. It wasn’t just an aesthetic, but a core component of the story and characters. I'm unable to vouch for their voracity, but I also enjoyed how various factual details (some of which are clearly embellished) of animal characteristics and behavior was used to model the cast. For example, Ranka's (wolf) iconic greeting, Miyubi's (sloth) frequent "deaths" due to overexertion, Yukari's (koala) interesting dietary choices, and Kurumi's (cat) aloof, independent nature, to name just a few. Even beyond that, this theme is used flavor the characters relationships with each other, such as the romance between King (lion) and Shiho (impala). The level of detail afforded to this component is commendable.
Jin and Ranka's interactions were the highlight of the show for me. Ranka's indomitable optimism, belief in her friends, and affection for Jin provides a humorous contrast against Jin's tsundere nature (spawned from his marked, yet ever-diminishing hatred of all animals). There obviously isn't much story given the nature of the show, but Jin and Ranka's relationship along with other elements, such as the King/Shiho romance and Yena's protracted character development, provide a small amount of continuity.
I thought the production quality was solid other than the intro/outro music which I did not like at all. The voice acting (Japanese) was pleasant. I especially liked the vocal rendition of Jin and Ranka. The art and animation were good: on par with most shows produced during the same time period.
