Mouth Diseases in Cats

According to the Cornell Book of Cats, a frequent sign of disorders in a cat's mouth is gingivitis, a term that refers to inflamed or red gums. Bad teeth as well as different viruses can present with this condition. Professional teeth cleanings from a veterinarian can reduce dental problems, but more serious symptoms, such as painful bumps or lesions in the mouth, may require blood tests to pinpoint the cause.

  1. Tooth and Gum Disease

    • The build up of bacteria-laden plaque and tartar at and below the gum line causes the gums to swell. Red gums and loose teeth result if left untreated.

    Squamous Cell Carcinoma

    • Squamous cell carcinoma is a cancerous tumor that affects the skin as well as the gums, mucous membranes, and area beneath the tongue of older cats. The tiny bumps and ulcers are painful and make it difficult for the cat to eat.

    Pemphigus

    • Pemphigus is an immune system disorder that can also affect the mucus membranes of a cat. It is a serious disease resulting in painful skin ulcers, but according to the Cornell Feline Health Center, the inflammation can be treated with steroids and drugs that contain gold.

    Eosinophilic Granuloma Complex

    • Eosinophilic granuloma complex (ECG) produces red and orange tainted areas inside the mouth. The Cornell Book of Cats states that diagnosis of ECG rarely requires a biopsy to confirm. The condition is treated with steroids, progesterone or in some cases radiation.

    Plasma Cell Gingivitis-Pharyngitis

    • Plasma cell gingivitis-pharyngitis presents with lesions resembling raw red meat. The cause of this disease is unknown, but according to the Cornell Book of Cats, drugs containing gold have shown promise for treatment.
