He'd probably pick up a soft spot, tbh because he is easier than he probably pretends to be.

Also I am all here for people being weird about suddenly-human cat, because honestly he's probably just getting used to that bit of it, and also he probably weirds people out on purpose sometimes- how maliciously probably depends on reaction and whether or not he has a soft spot. In this case, probably it's just occasionally funny to see her flustered.
