Cats can still survive if they have maggots on their bodies, but they need to clean their wounds in time, take out the maggots, and disinfect them with alcohol to avoid wound infection and inflammation. Change the cat's dressing on time every day and wait for the wound to recover. If the cat has a fever or is in low spirits, you can give it some antibiotics. Feed some light and easy-to-digest food in your diet to avoid affecting wound recovery.
