Cat has swolen mouth and not closing.

Thanks for reaching out—your concern is completely understandable. A swollen mouth that your cat can't close could be due to a variety of issues, ranging from dental problems like an abscessed tooth to an injury, an allergic reaction, or even an infection. Cats can sometimes develop swellings from insect bites or stings, which might cause the area to puff up and become painful.



At home, check if there are any visible signs in your cat’s mouth, such as a wound, a broken tooth, or anything unusual. Try to keep your kitty comfortable and ensure they are not licking or scratching the area excessively. Offering soft, wet food might help if they are struggling to eat, but avoid anything too warm that could exacerbate discomfort.



Watch closely for signs that the situation might be more serious—such as difficulty breathing, drooling excessively, a change in eating habits, or any more swelling. These could indicate an infection or an allergic reaction that needs prompt veterinary attention.



For peace of mind and to ensure your cat gets the care they need, I recommend booking a video consult with Dial A Vet. They can help assess the situation in detail and advise the best course of action.
