I have 2 sisters from the same liter and they get along great. We got Gracie 1st., she seemed lonely at times. When she was 6 months old, we had an opportunity to get her sister, Katie Rose. They recognized each other right away and they play constantly. Katie Rose has been so good for Gracie. She eats better, sleeps better @ night. We never regretted having 2. They are now 13 mos. old.and a real joy in our retirement.
