My name is Remy!

This is Remy, she is 3 years old. She's a loving funny cat. She has 2 sisters, one older and one youger. When Remy was adopted she took the place of the alfa. The reason I am looking to rehome her is because we had a stray cat walk into the house one day, and as expected they got into a fight. But, for some reason Remy also fought her older sister. And after that day, she won't stop fighting her. Her older sister is very quiet, shy and gets scared easily. And even the smaller cat is feeling frightened. Remy has never done that before. I want to keep the oldest because she has been through surgery after being attacked by a dog and broke her leg.
Remy is very people friendly. She likes being pet and cuddling. Has never bit or scratched any of us. We all love her, but can't have those fights. Specially when I have a 9 month old granddaughter in the house.
I wish she can get a good new loving family. We feel sad having to rehome her, but it's either her, or two others.
