John didn't mind cats. He liked them in fact. They were lazy and didn't need much care. But when you could compare your flatmate to one it was a bit odd. John had already gone over the similarities in his head. He even pictured Sherlock with ears and a tail. He had even once caught Sherlock drinking milk out of a bowl but it had been from his cereal.
John loved Sherlock he did. But when Sherlock wasn't Sherlock it was strange for the first few weeks.
When they first made it official and they had just started sharing a bed he never thought Sherlock was one to cuddle. But the man never missed a chance to wrap himself around John. Another thing John realized Sherlock stretched much like a feline would.
But only when he kipped on the couch after a long case, good chase and full belly. Like that didn't have cat written all over it. John watched as Sherlock pushed himself up as if he were going to do push-ups and drew his knees under him before arching his back.
He let himself flop over before pulling John into his arms and snuggling close.
It was during a rather lazy day that John discovered one other odd quirk about Sherlock. John had been sitting at one end of the couch with his back against the arm and his legs crossed Indian style Sherlock's head in his lap. John used one hand to hold his book and the other he carted through the man's dark curls.
He heard a strange sound soon after that sounded like a purr. Looking down at him John raise4d a brow but went back to his reading. When it started again he looked at Sherlock. "Are you…purring?"
"It happens." The detective told the blonde.
His lover was a cat on the inside.
