My Siamese is attacking my youngest kitty.
My Siamese which was my first cat is attacking the newest addition to our family. She is ok with the other two.
I have 4 cats: 3, 2, and 1, and 10 months. My siamese is the oldest and gets along with the other two but has attacked the youngest since I got her 4 months ago. They are all spayed and I have been keeping them apart two by two.
Recently I received a very bad infection from a scratch I received when picking up the youngest because she was so scared.
I need some help in deciding how to deal with this.
