I have a two year old cat that appeared on my porch last year. It turns out she was pregnant and did not go full term. She had a high fever and the vet performed surgery, etc. She has never been really affectionate but lately she doesn't like to be held or even petted. All she ever wants to do is be outside. Will she ever respond to me? I just wish she could be more affectionate. What can I do to make her more a part of the family?
