my cat only follows me around the house. she does exactly what she is told to do ex: go to bed, go outside, ect. (yes my cat its trained) only when i ask her to do it. when i am not home she doesn't move from her cat stand, she sits there all day. when im gone for the night she wont leave my room and she meows constantly until i get home the next day, and she paces also when im not home at night. does she have separation anxiety? if not whats wrong? and how can i help her feel less stressed when im not around?
