Urgent Care Needed for Saint's Injury

This is my cat saint, he is one of the sweetest cats you will ever meet. He came home last night with an animal bite on the side of his face, possibly from another cat. I couldn’t get him to a vet due to the fact we don’t have a car and we lack the money for an emergency vet. This morning when I checked him his face got swollen and I started calling around seeing how much it would be to get him in. He has an appointment tomorrow at 11:15am, most I’ll need is 300 dollars. If anyone could help it would be greatly appreciated. This cat is my baby and I mentally cannot see him go through this and I mentally cannot lose another cat right now.
