Hi. I have two little sister kittens who are best buddies, eat sleep and play together. They went in Monday to get spayed and since then the torty hisses and growls when the little ginger comes near. It's like she doesn't even know her. I have no idea what to do. I've tried rubbing thier blankets on them but she won't stop. Will this pass? Is this normal? Have I damaged thier bond? I'm worried sick. Please advise
