Hi, I have 4 yard cats, for mousers, I live on 5 acres, I got a new cat a month ago, and one of my other cats refuses to get along with her, I have now 3 girls and 1 boy, all fixed and between the age of 2 1/2 - 3 1/2 years old. The other cats took to the new cat within a week. But Dix does not want anything to do with her, & she will go and hide, for 2 days last week, I was so worried. Dix was my 2nd cat I got, and she was 4 months old when I got her, 2 years ago. So she's been around other cats. Any suggestions would be great and appreciated alot.
