Will be updated as I come up with more. Last updated 5/28/2011
1. Not so much headcanon as just something I've decided to take more literally I guess? To my understanding Nepeta isn't really part cat, and her tail is just part of her fursuit. Yet in animations we see it moving which I'm sure it meant to just be something cute or a joke but in RP you can't really do that xD So for me, I've decided to actually make the tail legit.
2. Equius taught her how to read/write and a lot of other things like basic math and other skills. Before him she was...I wouldn't say feral, but a lot wilder than she already is depicted in canon.
3. Equius built her her computer/tablet. Her coat was the first gift he gave her.
4. Equius is her moirail, but she considers Terezi her best friend and there is a very fine distinction with how she regards the two.
5. Her coat is humongous and has a lot of inside pockets which lead to another dimension. By which I mean she's always carrying around a lot of shit, sort of like Hagrid. Items she always has with her at any given time are: teacup, teapots, saucers, mixing spoons, herbs & teabags (
various sorts), mice (dead and alive. but mostly dead), pens and paints of all colors, brushes, one notebook, loose change/boon dollars/death bucks, bagged pastries and a wooden carved heart [SC only].
6. She reacts to catnip.
7. Repeated horn enhancement spam in her mail back when she lived on Alternia
made her slightly self-conscious about them 8. She has a very good sense of smell. Not as good as Terezi's wonder-nose but it helps her track down prey/people.
9. It's really, really hard to anger her. You can insult or yell at her all you want and she will just brush it off/ignore it.
10. She's a lot more perceptive than she might seen. Due to the latter she appears to be oblivious or someone who doesn't really pay attention but no--she just deliberately ignores that stuff.
11. There is actually quite a bit she doesn't know about her own culture, however, due to living away from any sort of civilization. The little she does know was probably taught to her by Equius.
12. Nepeta is incredibly friendly, and she'll try to make friends with just about anyone but she really isn't use to being surrounded by a lot of people. She's lived an almost hermetic lifestyle until now so being in a place as crowded, loud, and polluted as Death City/Balamb has slowly been chipping away at her patience and comfort. I wouldn't be surprised if sometime when she ends up going on a mission, she ends up wanted to stay there.
13. Catgirl can't swim, no surprise there.
14. She adores cute things of course, but she wouldn't never wear any dresses, skirts, or frilly things. That's about as outside of her comfort zone as you can get. Even not having her oversized jacket on makes her feel insecure.
15. She is a surprisingly good cook. She makes the best pot of tea you will ever taste, and mostly makes baked goods to go along with that (sorry John) but she can make other things as well!
16. For all her affectionate ways (hugging, pouncing [and those two she really only does with Equius and sometimes Terezi] bumping her head against others and other catlike signs of affectionate she's actually pretty damn shy with anything beyond that. She does those things she doesn't really see them as particularly intimate but just a way of saying I like you, or as a form of trying to cheer them up.
