It was a normal day where you were coming home. Until you see a box. A big one! There was a note there saying "A gift for an old friend" who? So you carried it inside as it was very heavy. You just left it in the corner as you were very tired and head to bed planning to open it tomorrow

The next day you woke up just to see it open. The couch has a scratch mark and the fridge. There was a tall girl with cat ears and tail mostly like a serval. As its eyes sharpen as she gets defensive

Her fur straightens up and she hiss "hisss~ who are you hooman! Don't you come here or I bite!" Her claws are out
