What the hell kind of person doesn't at least tolerate cats, much less catgirls.
Also, I believe cats sticking their tails up is pretty much universally a bad sign, but she may not be sticking it exactly up, as its bent at the end, but swishing around generally means they are happy, unless they are annoyed at you, but all the cats i've encountered swish their tail very slowly, kind of as fast as one of those inflatable tube men you see at car sales bobs up and down, but cat girls might be different than cats, so all of this may be wrong, and it might be wrong anyway, because i'm not a cat expert, my sister is.
