Emma needs to be saved

Back in March 2015, I saved Emma from the shelter. Emma was found as a stray and was being held in a cage for 2 months 24/7. She was never let out and lived on a wire bottom. She eventually was transferred to the adoption area. There she spent another 2 months. Only being let out once a day as long as there were volunteers. Again she lived on a wire bottom. The day shawn and I brought emma home, I made her cage up with blankets upon blankets so it was soft. She turned in circles so many times. When she layed down she let out a sigh of relief. Emma was guarded but after 2 years she finally let her guard down. She watches over my babies, checks on jaxson when he is crying and sleeps with Peyton every night as her protector. Emma knows when shawns PTSD is bad, she will not leave his side. She will follow him around just to keep an eye on him.  On November 26 2018 I took emma in for an exam because she had a lump in her arm pit. That lump turned out to be a mast cell tumor. Cancer. In order for emma to continue watching over her babies and getting all the love she has been since day one the tumor needs to come out. I know it is holiday season, but I'm asking for help. Normally I don't. I figure it out. But this time around i can't. Please help me save her. Her best friend passed February 2018, and I just can't lose Emma. She has been my rock through my miscarriages, my grandparents passing and other things. She lays with me when I'm crying and licks my tears away. Thank you.
