Hi KadoWolf. I know the one you're talking about, and I'm sure that it was on Doc's Lab at one point, though it seems to have been removed during that big cleanup so many months ago. I tried checking
the archives but am having trouble finding a story listing by species. The good news is that this may only be a temporary problem that's related to the Wayback Machine's server, as I did manage to find an old removed story from Doc's Lab a month or two ago with relative ease using that method. I would suggest that you check the archived sites periodically - you may eventually come across your story.
