I don't know how it happened. We returned home from a combo laundry and work and when we entered she was on the blanket and she did not look up at us. I knew something was wrong.
She was not breathing and there was no pulse. I was ready to give her cpr, but her body was already stiff.
I know 12 years means she isn't young, but cats live for a long time.
I only wished I knew what had happened.
