There sadly was nothing that could be done for Christofur , Pat.
Sadly some of us are predestined to have a short life , and you saved Christofur from dying in pain and fear, and let him become an Angels in a peaceful way.
I would put this Christine on spam and not let her bother you anymore.
There are always people who are so eager to blame, but not help.
Christofur is with The Found and Porch Angels this week, and then evvery week he will join a different band of Awesome Angels at home and in their Towns and Cities, and you and Your Cats will all unite with Christofur in love.
One Fine Day.
