You have to make her think it was her idea.Any ideas to convince a cat you no longer want it in your bedroom? Especially when she meows and scratches at the door constantly?
Also any way to convince her to not pay attention to cats roaming the neighbourhood at night coming right up the window just to taunt her?
And there isn't much you can do about outdoors cats. Try and shoo them away. Get some motion sprinklers that will spray them if they go by your windows.
