Very nice.

it's a pretty good shop there. but shouldn't the tag be added though?

Duplicate and what's up the Arigatou Kafun Shoujo pooling? I believe that is a doujin pool and has nothing to do with this picture.

Isn't the Cat tag used for the real animals like, not nekomimi and not anthrocat, just plain normal cats?

Chizuru is a fox spirit so it should be fox ears
