My boyfriend has a cat that comes by his house everyday and it has a massive oozing cut next to its ear and the ear has hair loss and looks very scabby. We are not sure what to do since we don't have money to take it to the vet. We have been feeding and giving water to the poor guy or girl. He/she is very friendly and I want to be able to do something for him but I'm not sure how. Any advice on what to do or how to clean the wound would be amazing.
