whats with this pet shop of horrors or something

[desperado]

last anime con tons of people talked about it, there was a person cosplaying as a character of it even... ummm it was a letter with chan like z chan or c chan or something.. anyways whats with this series, i never even heard of it till colosocon then people are saying its such a good series and that crazy chan person with the horns and claws, was a good cosplay but makes me wonder what in the world is it even about.....

well since its not in the reviews and i didnt see mention of it im wondering if anyone knows about it because if its decent i may check it out. and if its not ill have another reason to say "con people do not know what there talking about most of the time"
