Help save Luna

Hi there, this little shrimp is Luna. I found her 2 weeks ago near a dumpster looking for food. I decided to adopt her because i couldn't just stand watching her living like that. I took her to the vet for a check but i had some bad news. She was diagnosted with leukemia (FelV) and urine crystals. The second one can be changed with just urinary cat food (which is a bit expensive) but first one need some very expensive medicine. So i am doing this fundraising because i live alone and i can't afford them. I apreciate every little help anyone could give to help my little shrimp get over this.
