Q.T., Have you provided an adequate scratching post for your kitty? Also, you didn't mention if Sadie meows at night. Do you leave food and water out for her at night, and is she an only cat? Like it has been stated, I think that it could be a sign that she feels as though she is not getting enough attention.

My Cookie and Blue-Czarina, both take turns in meowing in the middle of the night, and sometimes when I am watching TV during the day. I have to call to them and have them come to me on the couch. Also, it is sometimes caused by either of them being hungry, and wanting special kitten chow to eat instead of the regular food that I leave out for all of my furkids.
