About 9 months ago a thin black cat came to moms door. He would not leave. Mom has alz and let it in etc... So now none of that but she comes every couple days you see where she comes from on the other side of condo complex. I decided to feed her as she would not leave otherwise..Friendly as well. I open the garage a little give good food then she leaves... She looks much better since I started feeding her. But she is extremely thin and now I noticed her eye was dilated then it went away... But now its completely dilated with a film over it... What should I do.. She goes home and gets around but it kills me to see this... With cold coming I just don't know... I have had cats my whole life and when its time you know.. I know if I go to the vet they will tell me to put it down...So should I wait and keep watchin her and see..... Its such a tuff call. As it is I take care of mom go back and forth now I worry about the cat.
