The Cat's Purr (Drarry) (Half-Cat!Draco)
Draco's just found out- by looking in the mirror- that he's part cat. His grandfather was bitten by a cat with a magical version of rabies, and the infused gene skipped a generation.
Ever since he's had the ears and tail, he's found that girls- and boys- are looking at him more often. Specifically one Harry Potter.
(This description is awful, I know.)
