I have a two year old black and white who obviously has siamese in her. One of the traits she has is that she is the most vocal cat I have ever come across. One of her favorite pasttimes is to find an echo in the house and coo and purr away as she listens to the echo. I enjoy her talkativeness but recently she has taken to yowling or crying at the strangest times with no apparent reason. I know she is not hurt physically. Sometimes I will only be in another room and she will start. The first time I heard her I thought something was wrong and when I found her she was sitting in the middle of the living room head in the air yowling away. When I said her name she then cooed and came over for a cuddle. This behavior has started to become more frequent and I am becoming concerned that I have encouraged it when I first went to find her. She has never done this before. We have had a lot of changes in the past few months, I got married and so we live in a new home but she has taken to my husband so well, she adores him. We then recently got a new kitty as a companion for her and at first she was afraid of him but now they are the best of friends. I am concerned about this because a.) I am worried there is something wrong with her that I'm just not getting and if there is I want to fix it and b.) She does it more and more at night also and I am worried that the neighbors are being kept up by it. Any help would be great.
