I'm honestly so mad at my cat because at night I have to lock her in my room cuz the litter box is in my bathroom(which is connected to my room). & ive been up & down all night because she keeps scratching at the door(which normally she just lays with her kittens and sleeps all night so idk why she wants out so damn bad) & to make it better I just heard her throw up in my bathroom & if she threw up on the rug; I'm gonna kill her, I just bought it yesterday🙃🙃
