Support Layla's Fight Against Feline Leukemia

I adopted Layla when she was about 6 months old. She's now about 2 and a half, and we recently found out she has feline leukemia. Feline leukemia (also known as FeLV) is a viral infection that implants itself into their DNA. It is not curable, only treatable. The treatment will be lifelong and will be expensive. Any help would be greatly appreciated.
