I think so. I know when I had my m/c when we first got home from the Dr all four cats were just sitting at the door, like they knew I was coming home with bad news. Of course they were extra sweet to me after that, but I also know they react to our emotions. But how did they know before I got home?
This time around I knew I was pg, but I was worried about my first appt due to spotting and of course my m/c. My one cat would not leave me alone! She was everywhere I went following me and meowing. Once we went to the Dr and found it was twins she backed off to her normal self, like ok she knows there's two and they are ok so I will leave her be
