You two have been dating for a while. When you two first started dating, he was confused when you just gave in to your cat instincts (ya know, since you’re a cat demon), like randomly hissing at things, knocking things over at random times, chasing a laser pointer, being terrified of toasters and jumping and bolting when one pops up, leaving dead mice on his desk, etc. He’s used to it now. In fact, he just randomly pets the top of your head and scratches behind your ears just to hear you purr.
