Unlike their face-to-face interactions, Kaeloo and Mr. Cat don't seem to have many arguments or fights via texts and their interaction via text seems happy and jovial. If they aren't face-to-face, Mr. Cat can't see Kaeloo transform and therefore would have no reason to piss her off.
One of the questions asks if Kaeloo and Mr. Cat whether they are in love or not. Mr. Cat casually remarks that he and Kaeloo text each other "non stop" whenever they're not together. Kaeloo and Mr. Cat have always been slightly obsessed with each other, and now they have the potential to "be with each other" regardless of where they are.
