Summary: A cat catches a mouse, mouse refuses to be eaten, cat shows signs of Periodontitis and mouse convinces cat to go to dentist. There are no subs (other than really bad auto-generated subs), but I feel like I can make the plot out enough to enjoy it and the little quirks it has. The only complaint I have is that the little jingles in the end are purposefully off pitch and overrun by the "Brought to you by the Japanese Society of Periodontists" voiceover (though it gets worse in season 2). That's the only thing that's making me rate this series a 6 instead ofa 7.

I think this series is good for people with intermediate or advanced knowledge of Japanese, but it will very much confuse beginners. But hey, you get to know what Periodontitis is! 歯周病 (Shishuubyou)! Go have fun writing it down and sharing it with your friends!
