Wow. Absolutely brilliant. I adored your Severus--as a cat and a human. You absolutely nailed the cat part (this says the cat lady) and he was ohh so much better as Severus the man. The entire story was artfully done, wonderfully structured, beautifully contrived. Harry going to King's Cross, the fog, the slow reveal of what exactly he was up to...all perfect in my book. And Severus' behavior once he was restored to human form, how he behaves with Harry, with Lucius, was so real, so believable. Kudos to you for this wonderful story of healing.
