All her traits thus far have either been inherited (night vision, cat ears) or are also commonly present in humans (liking tuna). It makes sense that she could have oter physiological traits. When writing cat traits into her personality the one I usually go for is an ability to purr, though it's not involuntary.

-Ruby stroking Blake's cat ears-

Ruby: Aww....

Blake: What is it?

Ruby: I-I thought you'd purr...

Blake: I CAN purr. I choose not to.

Ruby: Cats can do that?

Blake: Do I look like a cat?

Ruby: Umm... no?

Blake: Then how am I supposed to know?

-Ruby looks away guiltily before getting a sly smile, her eyes lighting up-

Ruby: COULD you purr?

Blake: Thin ice Ruby... *begins to purr*

-Ruby giggles whilst continuing to stroke Blake's cat ears-

It's also possible that she may indeed derive pleasure from having her cat ears scratched, same nerves at the end of the day. Her attention span may also be short, but that doesn't seem to be the case given her love of reading. Instinctual behaviour (landing on their feet, not sticking their heads in gaps their whiskers can't fit through) or preferences (catnip, playing with balls of yarn) are always off-limits in my opinion.

That being said TigerLily wrote a Bumbleby fanfiction (duh it's TigerLily when is she not writing Bumbleby) in which Blake gets high off of catnip and proceeds to do exactly what every high person does: make terrible puns, ramble on about absolute bollucks and fall asleep whilst attempting to seduce their girlfriend. Yes it was hilarious, it's why I can forgive the utter shameful degradation of Blake's character.
