please help baby nala

nala is 14-16 week old she is a rescue she was neglected. her home was a cardboard box full of poop anstd pee that constisted of no food or water. after bringing her to my home to feed her and clean her i noticed constant leaking. so i took her to the vet for her shots i had them check her urine,xray her abdomen, and then an ultrasound. they found she has an ectopic ureter and her right kidney is being damaged. nala is need of surgery. some have said put her down this is not an option i will raise the funds some how for her she has so much life and love to give and to be enjoyed. i have already paid over 500$ in exspenses to find the problem but don't have the funds to fix it. please open your hearts and share her storey. nala has got the short end of the stick already i'm hoping to turn that around.
