Save my late grandpa's cat

My grandparents have both pased away and they used to feed a lot of stray cats. A good portion of them were actually indoor cats who found their way outside. Since they have passed I've been trying to get them all fixed, vacinated and in good homes. Lately it's been getting difficult mostly because I'm running out of money. A few have also left on their own I dont know where.

It has been a few months now and there is still one cat who really needs a vet. I have tried to convince my parents and aunts to help me out but they have refused to help me. My parents told me they dont have the time and will not give me any money. 


This cat has an extra claw on one of his paws and my grandparents always called him 9 paws. I just need the money to take him to a vet and get him fixed and vacinated and for any possible illnesses he may have. I put out food and water for him once a week and he's very friendly. I dont want him to stay out side and it is starting to get cold. I cant take him in without him getting at least vacinated since I already have one of the other strays with me right now and it just cost us $6,000 to save him from complications and I dont want to put him in danger of getting ill again.


Any amount will help I'm seriously at my wits end. I dont know what to do. I've reached out to a ton of shelters but they werent willing to really help me. Please again anything will help.
