Surgery for Simba

My kitty Simba was hit by a car , I took him to the ER vet in Walnut Creek, I was able to do the most i could afford . He got x-rays done and I was given some medications that will last him Mabey two weeks for pain . Also an antibiotic . I was told he has a broken hip and will need surgery , he is currently bed bound unable to walk . He is lifeless and hardly eating I’m afraid with his hip not working he will give up and stop eating and drinking . So I need to get him fixed up ASAP ....I know cats , black cats at that dont matter to most but Simba and nala , his mama matter to me and my family . My oldest kid was raised with both of them and We would be so devasted if I have to say goodbye to my baby simba . He was the runt of the litter and I helped him grown . If you can donate , anything will help .
