There Is a Large Ulcerated Area, but My Cat Still Eats Normally with No Loss of Appetite
Expert Answer
It is recommended to open your cat’s mouth and check the oral mucosa. If the mucosa looks normal and there are no symptoms such as drooling, bad breath, red or swollen and painful gums, it is generally not caused by a mouth ulcer or stomatitis.
A single swollen or ulcerated lip is usually considered an eosinophilic granuloma, which is a type of skin inflammation in cats and may be caused by an allergy. When a granuloma appears, avoid feeding overly dry kibble; use a nutritionally complete cat food and supplement with appropriate trace elements and vitamins to strengthen your cat’s resistance and immunity.
If the granuloma breaks open and becomes inflamed, take your cat to a veterinary hospital promptly. The vet may prescribe corticosteroid anti-inflammatory medication such as prednisolone or dexamethasone, given orally for 3 to 5 days, along with an antibacterial and anti-inflammatory oral spray.
