Recently I found a beautiful female cat that I think has part simeze and birman in her. I have had her since January. She is a very loving cat and is by my side constantly. I also have two male cats 6 years old. This new female cat has started to grab my socks or my girls socks and she brings then downstairs and leaves them by the back door. This is the door that I leave to go to work. Is she expressing that she misses me while at work? She only brings the socks down when I'm not at home. I have not seen her do this but my husband has when I'm gone. Also, she will try to pick confrontations with my two other cats. I was hoping this would calm down but she still does not like them and it's been a couple of months.
