We just got two kittens two days ago, a boy and a girl. The boy is full of energy, and the girl is scared of him. She constantly wants to be alone and now even cries when we touch her. A few hours ago, I noticed that she is limping and I am afraid he might have hurt her. I am trying to keep them apart and let her rest, but I don't know what to do about the limp or their future relations.. please help!!!
