Of course it was the Gryffindors. That sort of stunt is just idiotic enough for them to find amusing. Besides, I did give Weasley fur once I wouldn't be surprised if it was a Weaselby, their brothers do have that idiotic joke store.
I'll inform you once I've decided on an appropriate response. We wouldn't want to be accused of something so unoriginal as having them sprout fur in return. We are Slytherins, after all.
