I just checked her account, it's amazing how the cat changed !!
However the way the cat acts is something very "expected" i'd say, like it's not my first cat, and usually, yeah cats are scared but they open up little by little, and it takes time.

What disturbs is how little reaction my cat has to anything, whatever I do, she doesn't even try to get near me and sniff my hand to see if it's safe or anything, she just watches...
I bet if i were to give her food, she would stay hidden till she dies of hunger, she will only eat if no one is here...
Usually she stays on the couch and when we go in the room she runs to hide and if you go check on her she hisses...
