Help sparky after aggressive dog attack

On the 29th of December my cat was playing outside when an aggressive dog attacked my young adult cat leaving him with three holes in his abdominal Muscle. What required emergency surgery to save his life, he was operated on straight away saving his life but things turned to the worse when he came home he got jaundice and needed more treatment, he was in vets for a week on iv fuilds and other medications. He recovered and finally started eating after a week and half of not. 1 week later he under went two more surgery for his break down of worn and hole in his body, sadly sparky has been pefted with a hole the size of a apple in his side that's gonna take 2months to heal with heaps of antibiotics and other Materials to stop and infection.

After this is the 3rd dog attack this dog has done we are every lucky to have him alive. Can you help poor sparky in anyway he would really appreciate I don't like asking for help but I really am struggling with vet costs.
