LaPerm kittens & cats in Nevada

Lucifer, aka Lu or Luci: I adopted Lu, at 6 months old, last year from my local shelter to be a companion to our dog. We soon found out she's afraid of dogs and after four months in her new home, I had to move suddenly and couldn't take her with me. My mom volunteered to foster her and had her for roughly 6 months. Things started out fine, until one day she started playing really rough and sometimes biting/scratching her ankles or even her during her sleep. My mom sold her house and I had to find someone to take Lu in the meantime as I still couldn't have her where I am living. My friend took her in, things started off great, then she started exhibiting that same behavior. She's never been aggressive toward me so I'm not sure what to make of this. But I live with a german shepherd who would attack her in an instant and won't be moving for another several months. Lucifer needs someone who is patient, understanding and loving so she can show her true colors once she warms up to them.
