As far as Harry knew, it was all some sort of experiment that only Dumbledore could understand. He had no idea that the cat he had been given to keep him company instead of Hedwig over the holidays before his 3rd year, was in fact, his hated Potions Master in disguise.

Because of the Azkaban escapee, Sirius Black, Severus is sent to stay with Harry during the entire summer, never making a sound nor leaving the boy's side. He could not speak, nor could he defend Harry against anyone other than the criminal on the loose, however Severus does something that no other adult in Harry's life had done before...he listened.
