Judging from the layout from mitemin, it seems to be a site where new artists post their own fan creations. The main basis of the site seems to fanart, with some being quite impressive in detail.

While the account name posted shares the same name (鼠色猫) as Tappei's twitter account. For all we know, it could just be an overzealous fan who copied Tappei's twitter user name for that site. Adding to that, the account itself is pretty devoid of all content, even lacking a user name pic. My guess is that it's a fan who found the images and made slight modification to them.

That being said, if you have a tweet from Tappei claiming ownership of the account it would be a different story.

Edit: Either way, I just asked a friend of mine who speaks Japanese to send a message to that user. If it is really Tappei, that would be hilarious.
