The problem of oral diseases in small pets is widespread. The subject of the study was the diagnosis and treatment of indolent ulcer in a 15-month-old Maine Coon cat. 4 days after the scheduled vaccination, along with the general clinical symptoms of the disease, the cat developed erosion with a diameter of 0.5–0.7 cm on the upper left lip. The diagnosis of "ulcerative stomatitis" was made. At the time of the study, the owner noted weight loss in the cat, swelling of the upper lip, purulent crusts on ulcerative foci, purulent discharge with an unpleasant odor. Examination of the animal revealed swelling of the upper lip, increased local temperature, raised upper lip, symmetrical ulcerative erosive lesions up to 5–5.5 cm in size on the mucous membrane, whitish-reddish overlays, crusts and exudate with an unpleasant odor, enlargement of regional lymph nodes. A large number of eosinophils, neutrophils, macrophages and cocci were found in imprint-smears from the oral mucosa; leukocytosis, hypoproteinemia, hypocalcemia were found in the blood; and proteinuria, ketonuria, urobilinogenuria, nitrituria, leukocyturia were found in the urine. Microbiological examination of the ulcer discharge revealed St. aureus and St. saprophyticus. PCR-RT was negative for the detection of viral leukemia, calcivirosis, viral immunodeficiency and coronovirus infection. Based on the examinations, the cat was diagnosed with a bilateral indolent ulcer. In the complex of therapeutic measures, local irrigation of the oral mucosa, tissue infiltration, vitamins and minerals, detoxification and anti-inflammatory therapy, and ultraviolet irradiation were used. After a long course of treatment, the cat went into complete remission. Therefore, timely correct diagnosis, combination therapy, feeding and housing conditions are effective in obtaining indolent ulcers in cats.
