Let's face it, reviewing this anime is pretty pointless, since it only has 5 minutes of content. But meh. It most likely servers is a teaser for manga, hinting that it might at some point grow into anime, but not anytime soon. Keep in mind I haven't read the manga. In the 5 minutes you get to see (presumably) all the main characters revolving around a bath for cats. As you can imagine, there isn't much space to show the depth of characters or any part of plot whatsoever. The animation is pretty neat and audio fits in well, yet it isn't anything spectacular. If they ever makean anime and I'd have to judge it based only on those 5 minutes, I'd expect a mellow piece focused on small talk with a bit of development around the inn and Makoto x Yuri front. Again nothing too shabby, but nothing earth-shattering either.

Should you watch it? Most likely no, unless you are looking for a new manga to read or have too much time on your hands. Until they announce an anime, there are better things to watch in same format (for instance Gakkatsu).
