Help My Cat Recover After a Double Dog Attack

My cat was attacked by two large dogs that escaped their fence and went into my enclosed porch. One had her by the neck the other her leg. She ran 25 feet up a tree. When she came down she'd ran off. After 3 long and stressful days she has finally made it home, but she’s severely injured and needs urgent veterinary care. I’m doing everything I can to help her heal, but the vet bills are more than I can manage alone. Any amount helps — thank you so much for your kindness ❤️
