I don't think she's been hit by a car, her claws and paws are fine and she's acting normally now. I've actually only looked after for 5 months, before that she lived in a cruel house where she was mistreated terribly. It's taken all this time to build up the trust; she no longer cowers under tables and she now purrs and is getting used to being held. She's no longer angry and does not lash out anymore. I had no choice about taking her on; around Christmas she sat on my doorstep and refused to budge. I hope her previous owners have not caused her any "brain damage". I will explain all this to the vet and keep you posted!
