Karmas emergency tail amputation

Anyone who knows me, knows how much karma means to me. She has a life or death matter that is time sensitive. Her tail has become infected and is dying (necrosis). She needs it amputated before the infection spreads to her blood. The sooner that it is removed the less chances of any more complications. Karma and I appreciate any help at all. This is the last thing I want to do but the fact is we need the help. Love and light.
