Wilson With a Tail?

[barefootpuddles.livejournal.com]

Over at house_wilson there is a discussion (thanks to agent_era) of Wilson and what possible superpowers he might possess in a fanfiction story (I really hope agent_era and other write these). But it got me thinking about a fic I had seen years ago where Wilson had a tail. It might actually have been an entire series, or at least more than one fic. In one story there was a family that came to the hospital to have their child's tail removed and Wilson tried to talk them out of it. In another (or maybe part of that same story) he reflected on growing up with a tail. Does this ring a bell with anyone?
