How can I make new cat love me?!

Your cat will come to love you on its own time and even then it might not directly show your affection. Once it starts doing things like sitting in your lap or wanting to "make biscuits" on you, like my cat does, then thats an indicator your cat loves you. Some kitties have sweeter dispositions than others while others are more "tough love". I've had cats that would lick my face clean while I tried to sleep and I've had some that would chase, attack and gnaw on my food, like they hated me but would always want to come into my room late at night to "make biscuits" and get comfy when no one was around.
