What are the reasons for a cat's swollen mouth?

The main causes of a cat's swollen mouth include allergies, trauma, oral diseases, and granulomas. First, if a cat comes into contact with allergens such as food or toys, it can cause allergic swelling around the lips. Secondly, if a cat accidentally gets stabbed in the lips by sharp foreign objects, trauma can also cause inflammation and swelling. Furthermore, when a cat suffers from oral diseases such as gingivitis or angular stomatitis, the disease spreading to the lower lip can lead to lip swelling. Lastly, if a cat has local itching, hair loss, and redness, it may be suffering from eosinophilic granulomas, a skin inflammatory disease.

Allergies

If a cat accidentally eats allergic food or comes into contact with specific allergenic substances, or develops drug allergies due to recent medication, it can cause lip allergies and swelling. In this case, the cat may also show symptoms such as facial redness, vomiting, and skin rashes. To treat this, identify the allergen and adopt different treatment methods according to the type of allergen.

Trauma

If a cat's mouth sustains an injury, such as being scraped by sharp objects like bones or fish bones, the affected area may become red, swollen, and inflamed. To check for foreign objects or wounds, the owner can open the cat's mouth and examine it. If there is a foreign object, remove it first and apply antibacterial and anti-inflammatory drugs to the wound.

Oral Diseases

If a cat has oral diseases such as gingivitis or angular stomatitis, the disease may spread to the lower lip, causing swelling. The cat may also exhibit symptoms such as bad breath, drooling, swollen gums, and ulcers. To treat this, the owner can check the cat's mouth for inflammation or ulcers. If found, take the cat to a pet hospital for immediate treatment.

Granulomas

Feline granulomas are generally considered eosinophilic granulomas, a common skin disease in cats that causes abnormal thickening, swelling, and hair loss around the lip margins. Treatment generally involves using anti-inflammatory drugs to control the inflammatory condition and antibacterial drugs to prevent secondary infections at the broken skin. During treatment, apply medication on time, clean the cat's mouth daily, and prevent food from rotting and fermenting to worsen the condition. Also, provide food that is easy to chew.
