Well, she is gone. The vet started talking 'options' and I just said that a few weeks were not worth it for her. She was old and tired. I think she was in the beginning stages of pain.
So, now she is at peace and playing over the Rainbow Bridge with her children and other fur-kids.
I want to thank everyone who sent hugs and good thoughts. It was very much appreciated.
