Sebastian likes the sound a cat makes. It's very soothing and sweet. He doesn't like the way his face burns hot when the Cat comments about the soap. The Cat knows something. And why shouldn't he know? It's not like they're hiding anything from anyone or doing anything wrong.

After a moment's hesitation in which he does almost snuggle the cat in his arms, Sebastian looks at the Cat and smiles just a little. "Alec hasn't given me any of his soap."
