Rat in need please

Hi my name is Kayla, I am fifteen and have had rats for several years because they are such great companions. I spend a lot of time with them and feed them a very healthy and organic diet. Skittles, as shown in the picture, is still young and is my first rat to have tumors. I am hoping to raise enough money to get both her tumors removed and improve her quality of life. They make it very difficult for her to move around and could potentially lead to more serious damage. I am asking for donations to get them removed so that she can once again run around with her sisters. Any help is greatly appreciated. Thank you!
