Help please if you don't mind :)

Hi, I am looking for a Harry Potter story where harry is little and he gets adopted by Severus because his previous guardian had to be taken to the hospital. A police woman takes care of him at first Harry is mute and is very attached to cats. He refers to remus and Severus as man and other man, he seems more attached to Remus than Severus.If you could help me I would appreciate it
